DRAM MODULE
M53620400DW0/DB0 & M53620410DW0/DB0 with Fast Page Mode
4M x 36 DRAM SIMM using 4Mx4 and 16M Quad CAS, 4K/2K Refresh, 5V
GENERAL DESCRIPTION
FEATURES
The Samsung M5362040(1)0D is a 4Mx36bits Dynamic RAM
high density memory module. The Samsung M5362040(1)0D
consists of eight CMOS 4Mx4bits DRAMs in 24-pin SOJ pack-
age and one 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 M5362040(1)0D is a Single In-line
Memory Module with edge connections and is intended for
mounting into 72 pin edge connector sockets.
