DESCRIPTION The GS-F8MB-SIMM is an 8 Mbyte SIMM memory module built around 16 x M29F040 FLASH memory chips (please see relevant data sheet for all detailed informations about the chip performances). 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.

Memory control is provided by 4 Chip Enable (CE0, 1,2,3) inputs used to address the 4 memory banks and by 4 Write Enable inputs used to select through the DQ..... groups. An Output Enable input is used to read the stored data. Erase and Program Functions are performed through the internal Program/Erase Controller (P/E.C.). The Data Output chip bits DQ7 and DQ6 (and the corresponding DQ15 & 14, DQ23 & 22, DQ31 & 30) provide polling or toggle signals during Automatic
Program or Erase to indicate the Ready/Busy state of the internal Program/Erase Controller. Configuration & speed pins PD1-PD7 pins are used by the SIMM module to inform the motherboard about its relevant configuration and also about the speed of the chips used, as specified in the Jedec 21-C standard. As the module allocates 8Mbyte memory, using 70 ns chips, configuration is the following: PD1 : Vss PD2 : NC PD3 : NC PD4 : Vss PD5 : NC PD6 : NC PD7 : Vss
