Patent number: 4984149Abstract: A memory access control apparatus according to the present invention which controls an IC memory of which is under the control of a BIOS in the same manner as in a normal disk unit. External file units including the IC memory, a floppy disk unit, a hard disk unit, and the like are assigned a series of drive numbers. Registers store parameters for using the IC memory as an external file, and an access address and a transfer length of the IC memory are expressed in a sector form. The BIOS receives the access address and the parameters, translates the address into a byte form address, and transfers data to a corresponding area.Type: GrantFiled: March 28, 1988Date of Patent: January 8, 1991Assignee: Kabushiki Kaisha ToshibaInventors: Takashi Iwashita, Koichi Awazu, Kiyoshi Murase
