rolled-over memory
A type of dynamic random access memory (DRAM). The reader has 1MB of
battery-backed DRAM. From the memory existing between the 640K and 1MB
boundaries, 384K is remapped or "rolled-over" above 1MB to create the RAM
drive. If you do not need the RAM drive, you can access rolled-over memory
as extended memory through a device driver or an application that uses
HIMEM.SYS.
ROM
Read only memory. Usually a small memory that contains often-used
instructions, such as microprograms or system software. ROM is programmed
during memory fabrication and cannot be reprogrammed.
ROM drive
A read-only memory drive. Drives C and D are ROM drives implemented in
flash memory on the reader.
