DRAM MODULE
M53620812CW0/CB0
M53620812CW0/CB0 with Fast Page Mode
8M x 36 DRAM SIMM using 4Mx4 FP and 4Mx4 Quad CAS, 2K Refresh, 5V
GENERAL DESCRIPTION
FEATURES
The Samsung M53620812C is a 8Mx36bits Dynamic RAM
high density memory module. The Samsung M53620812C
consists of sixteen CMOS 4Mx4bits DRAMs in 24-pin SOJ
package and two CMOS 4Mx4 bit Quad CAS DRAM in 28-pin
SOJ package mounted 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 M53620812C is a Single Inline Memory Module with edge connections and is intended for
mounting into 72 pin edge connector sockets.
