Description
The GMM7654287CTG is an 4M x 64 bits EDO
Dynamic RAM MODULE which is assembled 4
pieces of 4M x 16bit EDO DRAMs in 50 pin
TSOP
樓鹵
package, one 2k EEPROM for SPD in 8-
pin TSSOP package mounted on a 144 pin printed
circuit board with decoupling capacitors.
The GMM7654287CTG is optimized for
application to the systems which are required high
density and large capacity such as main memory of
the computers and an image memory systems, and
to the others which are requested compact size.
The GMM7654287CTG provides common data
inputs and Extended Data Outputs.
