MEM [/CLASSIFY | /DEBUG | /FREE | /MODULE module name] [/PAGE]

/CLASSIFY or /C	按内存使用情况对程序进行分类。列出程序的大小，提供正在使用的内存摘要，并列出可用的最大内存块。
/DEBUG or /D	显示内存中所有模块的状态，内部驱动程序和其他信息。
/FREE or /F	显示关于传统内存和上层内存中剩余的可用内存数量的信息。
/MODULE or /M	显示模块内存使用情况的详细清单。这个选项后面必须跟一个模块的名称，可以选择用冒号与/M分隔。
/PAGE or /P	在每个屏幕充满信息后暂停。

Displays the amount of used and free memory in your system.

MEM [/CLASSIFY | /DEBUG | /FREE | /MODULE module name] [/PAGE]

/CLASSIFY or /C	Classifies programs by memory usage. Lists the size of programs, provides a summary of memory in use, and lists the largest memory block available.
/DEBUG or /D	Displays the status of all modules in memory, internal drivers, and other information.
/FREE or /F	Displays information about the amount of free memory left in both conventional and upper memory.
/MODULE or /M	Displays a detailed listing of a module's memory use. This option must be followed by the name of a module, optionally separated from /M by a colon.
/PAGE or /P	Pauses after each screen full of information.

Windows 2000和Windows XP示例输出:

655360 bytes total conventional memory
655360 bytes available to MS-DOS
633872 largest executable program size
1048576 bytes total contiguous extended memory
0 bytes available contiguous extended memory
941056 bytes available XMS memory MS-DOS resident in High Memory Area

mem /f

显示常规的内存空闲量。

在Windows中的DOS窗口中使用mem /c命令时，不会看到上层块，如上例所示。
在Windows中显示0字节，因为Windows为Windows保留了所有全局上部内存块。

当输入mem时，MS-DOS 6.2及以上版本不接受或识别超过64 MB的ram。
