DESCRIPTION
AVED Memory Products AMP374P6453BT1-C1H/S is a 64M bit X 72 Synchronous Dynamic RAM high density
memory module. The AVED Memory Products AMP374P6453BT1-C1H/S consists of eighteen CMOS 32M X 8 bit
with 4 banks Synchronous DRAMs in TSOP-II 400mil package and a 2K EEPROM in 8-pin TSSOP package on a
168-pin glass-epoxy substrate. Two 0.1uF decoupling capacitors are mounted on the printed circuit board in
parallel for each SDRAM.
The AVED Memory Products AMP374P6453BT1-C1H/S is a Dual In-Line Memory Module and is intended for mount-
ing into 168-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 latencies
allows the same device to be useful for a variety of high bandwidth, high performance memory system applications.
APPLICATION
Main Memory unit for computer, Microcomputer memory,
Refresh memory for CRT.
