FEATURE
GENERAL DESCRIPTION
• Performance range
Part NO.
The Samsung M965(6)G0225MP(Q)0 is a 2M bit x 64 Syn-
chronous Graphic RAM high density memory module. The
Samsung M965(6)G0225MP(Q)0 consists of four CMOS 1M x
32 bit Synchronous Graphic RAMs in 100pin QFP packages
mounted on a 144pin glass-epoxy substrate. Five 0.1uF
decoupling capacitors are mounted on the printed circuit board
for each Synchronous GRAM. The M965(6)G0225MP(Q)0 is a
Small Outline Dual In-line Memory Module and is intended for
mounting into 144-pin edge connector sockets.

Synchronous design allows precise cycle control with the use
of system clock. I/O transactions are possible on every clock
cycle. Range of operating frequencies, programmable laten-
cies and burst lengths allows the same device to be useful for a
variety of high bandwidth, high performance memory system
applications.
