Abstract: A computer system (20) utilizes a monitor (24), keyboard (26), hard disk drive (28), processor (30), computer memory block (32), and memory based disk emulation device (22) to reduce access time for swap and paging files, thereby enhancing the computer system performance. The disk emulation device includes a device (22) manager (38) operable to select the number of logical drives, and a disk emulator (40) operable to cause actual memory devices (44-50) to appear as the virtual memory of the computer system disk drive (28). A memory controller (42) divides data bytes into data sets of two or four bits and saves the data sets simultaneously to the emulation memory devices (44-50). A backup battery (52) is provided to power the memory controller (42) and emulation memory devices (44-50) in the event of primary power supply failure.
