DRAM MODULE
KMM5362203C2W/C2WG
KMM5362203C2W/C2WG with Fast Page Mode
2M x 36 DRAM SIMM using 1Mx16 and 1Mx4 Quad CAS, 1K Refresh, 5V
GENERAL DESCRIPTION
The Samsung KMM5362203C2W is a 2Mx36bits Dynamic
RAM high density memory module. The Samsung
KMM5362203C2W consists of four CMOS 1Mx16bits DRAMs
in 42-pin SOJ package mounted and two CMOS 1Mx4bit
Quad CAS DRAM in 24-pin SOJ package on a 72-pin glass-
epoxy substrate. A 0.1 or 0.22uF decoupling capacitor is
mounted on the printed circuit board for each DRAM. The
KMM5362203C2W is a Single In-line Memory Module with
edge connections and is intended for mounting into 72 pin
edge connector sockets.
