Conventional memory is a section of IBM compatible memory that totals 640 KB. This portion of the memory is the only portion accessible by MS-DOS without the aid of a memory manager. To maintain compatibility, computers developed after the 8088 continued to observe this barrier.

Additional information about RAM (random access memory), and other portions of memory, is available on our RAM diagram.
