DESCRIPTION
The GS-F8MB-SIMM is an 8 Mbyte SIMM memory
module built around 16 x M29F040 FLASH mem-
ory chips (please see relevant data sheet for all
detailed informations about the chip perform-
ances). The devices are mounted on a Jedec 21-C
standardized SIMM printed circuit.
Organisation
Figure 1 shows the block diagram. The FLASH
module is organized as 16 x 512K x 8 bits with
address lines A0-A18 and Data Inputs/Outputs
DQ0 to 7, DQ8 to 15, DQ16 to 23 and DQ24 to 31.
