Common reasons why this memory cannot be read or written.
People who use the Windows operating system sometimes encounter the following error message: "The memory referenced by the instruction 0x000000000x cannot be written", and then the application closes. If you ask some "experts", the answer you get is often indignation and disdain like "Windows is so unstable". In fact, this error is not necessarily caused by the instability of Windows. This paper will briefly analyze the common causes of this error.
First, the application cannot check the memory allocation.
When a program needs a piece of memory to store data, it needs to call the "function function" provided by the operating system to apply. If the memory allocation is successful, the function will return the address of the newly opened memory area to the application, and the application can use this memory through this address. This is "dynamic memory allocation", and the memory address is also a "pointer" in programming.
Memory is not always available and inexhaustible, and sometimes memory allocation will fail. When the allocation fails, the system function will return a value of 0. At this point, the return value "0" no longer indicates the newly enabled pointer, but a notification sent by the system to the application, indicating that an error has occurred. As an application, you should check whether the return value is 0 after each memory application. If so, it means that there is a fault and some measures need to be taken to save it, which enhances the "robustness" of the program.
If the application does not check this error, it will think that this value is an available pointer assigned to it according to "thinking inertia" and continue to use this memory in subsequent operations. The real 0-address storage area stores the most important "interrupt descriptor table" in the computer system, which is absolutely not allowed to be used by applications. In an unprotected operating system (such as DOS), writing data to this address will lead to an immediate crash, while in a robust operating system, such as Windows, this operation will be immediately captured by the protection mechanism of the system, and as a result, the operating system will forcibly close the wrong application to prevent its error from expanding. At this time, the above-mentioned "write memory" error will appear, indicating that the referenced memory address is "0x00000000".
There are many reasons for the failure of memory allocation, such as insufficient memory and mismatched system function versions. Therefore, this distribution failure is mostly seen after the operating system has been used for a long time, a variety of applications (including virus programs installed unintentionally) have been installed, and a large number of system parameters and system files have been changed.
Second, the application refers to an abnormal memory pointer due to its own BUG.
In applications that use dynamic allocation, it sometimes happens that the program tries to read and write a memory that should be available, but for some reason, the expected available pointer has failed. It may be "forgetting" to ask the operating system for allocation, or it may be that the program itself canceled this memory at some point, "not paying attention" and so on. The logged-out memory is reclaimed by the system, and its access right no longer belongs to the application, so reading and writing operations will also trigger the protection mechanism of the system, and the only final result of the program that tries to "violate the law" is to be stopped by the operation and recover all resources. The laws of the computer world are still much more effective and severe than human beings! A situation like this is a BUG in the program itself, and you can often reproduce the error in a specific operation sequence. The invalid pointer is not always 0, so the memory address in the error prompt is not necessarily "0x00000000", but it can also be other random numbers.
If the above error prompt appears frequently, the following suggestions may be helpful:
1. Check the system for Trojan virus. In order to control the system, such programs often modify the system irresponsibly, resulting in abnormal operating system. We should strengthen our awareness of information security at ordinary times, and never be curious about executable programs with unknown sources.
2. Update the operating system, so that the installation program of the operating system can copy the correct version of the system files and correct the system parameters. Sometimes there are bugs in the operating system itself, so pay attention to installing the officially released upgrade program.
3. Try a new version of the application.
When running some programs, sometimes there will be a memory error prompt, and then the program will close.
0x instruction refers to 0x memory. The memory cannot be read.
0x memory referenced by 0x instruction cannot be "written".
I wonder if you have ever seen such a fault. (The contents after 0x may be different. )
Generally speaking, this phenomenon has many aspects. First, there is something wrong with the hardware, that is, the memory; second, there are many problems with the software.
Let's talk about hardware first:
Generally speaking, memory problems are unlikely. The main aspects are: the memory stick is broken, the memory quality is problematic, and there are two different brands of memory with different capacities, which is also prone to incompatibility. At the same time, we must pay attention to heat dissipation, especially after overclocking. You can use the software MemTest to check the memory, and you can thoroughly check the stability of the memory.
This problem occurs if you have dual memory, and different brands of memory chips are mixed or you buy second-hand memory. At this time, you should check whether there is a memory problem or it is incompatible with other hardware. If not, troubleshoot the software.
Let's talk briefly about the principle first: there is a place in memory called buffer for storing data. If the program puts the data in one place, it will overflow because of insufficient space. For example, a bucket can only hold one catty of water. If you put two Jin of water in it, it will overflow. The system is displayed on the screen. This problem often appears in windows2000 and XP systems. Windows 2000/XP has very strict requirements on hardware. In the case of deadlock, overflow or illegal operation of resources similar to Windows 98, the above situation will occur in order to keep the system stable. In addition, it may also be caused by poor compatibility between hardware devices.
Let me give you an analysis from several examples:
Example 1: Open IE browser or "0x00000000" memory referenced by "0x70dcf39f" instruction will appear in a few minutes. The memory cannot be read. To terminate the program, click OK. After clicking OK, the message box "An internal error has occurred and a window you are using will be closed soon" will appear. After closing this prompt message, IE browser is also closed. Solution: Repair or upgrade IE browser and patch it at the same time. I see that there is a repair method that Win2000 is self-upgrading, that is, Win2000 is upgraded to Win2000. In fact, this method is to restore the system to the initial state. For example, if your IE is upgraded to 6.0, it will be changed to IE5.0 after the upgrade.
Example 2: Double-click the "AutoRun.exe" file in the CD-ROM under windows xp to display the "0x00000078" memory referenced by the "0x77f745cc" instruction. Memory cannot be "written". To terminate the program, click OK, but it works normally in Windows 98. Solution: This may be a compatibility problem of the system. For winXP system, right-click the AutoRun.exe file, properties and compatibility, and select "Run this program in compatibility mode" and "Windows 98/Me". Win2000, if the SP is patched, just start running, and enter: regsvr32c: \ \ winnt \ \ apppatch \ \ slayeui.dll. Right-click and the properties and compatibility options will also appear.
Example 3: An error occurred when closing RealOne Gold. It used to be normal, but recently the "0xffffffff" memory referenced by the "0xffffffff" instruction appears every time it is closed. This kind of memory can't be a hint of "read". Solution: When the input method used is Microsoft Pinyin Input Method 2003 and the language bar is hidden (no problem when it is not hidden), this problem will occur when RealOne is closed, so you can display the language bar before closing RealOne or use any other input method as the current input method to solve this problem.
Ex. 4: My hero, Super Jieba, has been unable to play since he got online. Every time you are prompted that the "Oxff0000 1 1" memory referenced by the "Ox060692f6" command cannot be "read", press OK to terminate the program. Solution: Try to reinstall Hero Super Jieba. If it is reinstalled, you can try to download the corresponding version of the patch from official website. Not yet, so I have to try another player.
Example 5: Double-click the shortcut of a game, and the instruction "Ox77f5cdO" refers to the memory "Oxffffffff", which cannot be read, prompting that the Client.dat program is wrong. Solution: Reinstall the latest driver of graphics card, and then download and install DirectX9.0.
Example 6: My friend sent me a message, and my computer got an error message: the "0*00303033" memory referenced by the "0*772b548f" command could not be "written", and then QQ automatically went offline, and then I opened QQ and found more than a dozen messages sent by him. Solution: This is that the other party uses a BUG in QQ to send a special code and makes an error in QQ. Just patch or upgrade to the latest version, and you'll be fine.
From the above example, we can see that there are many reasons for failure. Here we make a list of the mentioned and possible reasons for your reference.
solution
1. If the memory stick is broken, please replace it.
2. Dual memory is not compatible with using the same brand of memory or only using one memory.
3, memory quality problems replace the memory stick
4. Heat dissipation problem Strengthen the heat dissipation inside the chassis.
5. Memory and motherboard are not inserted correctly or are incompatible with other hardware. , and then the memory is plugged in or plugged in badly.
6. If there is something wrong with the hard disk, please replace it.
7, the driver problem reloads the driver. If it is a new system, the motherboard driver should be installed first.
8. The software is damaged and reinstalled.
9. There are bugs in the software that need to be patched or the latest version.
10. Software and system are incompatible. Patch the software or try the compatibility mode of the system.
1 1. Software and software are in conflict. If you have installed any new software recently, please uninstall and try it.
12. If the software needs to be used in other related software, reinstall the related software if there is any problem. For example, there is an error when playing a file in a certain format, which may be a problem with the decoder of this file.
13, antivirus for virus problems
14, antivirus software conflicts with system or software. Because anti-virus software enters the bottom monitoring system, it may conflict with some software, so try to uninstall it.
15, there is something wrong with the system itself. Sometimes the operating system itself has bugs. Pay attention to install the official upgrade program, such as SP patch, and it is best to install it. If not, please reinstall the system or replace it with another version.
Blue screen is common when using Windows, and it is laborious and time-consuming to reinstall the system frequently because the source of the error is not clear. The following collected some windows crash passwords for your reference.

This kind of memory can't be a hint of "read". Solution: When the input method used is Microsoft Pinyin Input Method 2003 and the language bar is hidden (no problem when it is not hidden), this problem will occur when RealOne is closed, so you can display the language bar before closing RealOne or use any other input method as the current input method to solve this problem.
Ex. 4: My hero, Super Jieba, has been unable to play since he got online. Every time you are prompted that the "Oxff0000 1 1" memory referenced by the "Ox060692f6" command cannot be "read", press OK to terminate the program. Solution: Try to reinstall Hero Super Jieba. If it is reinstalled, you can try to download the corresponding version of the patch from official website. Not yet, so I have to try another player.
Example 5: Double-click the shortcut of the game. The instruction "Ox77f5cdO" refers to the memory "Oxffffffff" and cannot be read, indicating that the Client.dat program is wrong.
