AMP374P1623AT2-C1L
16M X 72 SDRAM DIMM with ECC based on 8M X 8, 4 Banks, 4K REFRESH, 3.3V Synchronous DRAMs WITH SPD
DESCRIPTION
AVED Memory Products AMP374P1623AT2-C1L is a 16M bit X 72 Synchronous Dynamic
RAM high density memory module. The AVED Memory Products AMP374P1623AT2-C1L
consists of eighteen CMOS 8M 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 AMP374P1623AT2-C1L is a Dual In-Line Memory Module
and is intended for mounting 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.

Input Function
Active on the positive going edge to sam ple all inputs.
Disables or enables device operation by masking or enabling all inputs

Masks system clock to freeze operation from the next clock cycle. CKE
should be enabled at least one cycle prior to new comm and. Disable
input buffers for power down in standby.
CKE should be enabled 1CLK+t ss prior to valid com mand.
Row/Column addresses are m ultiplexed on the sam e pins.
