SM364TCSMB3UI15
256KByte (32Kx64) Synchronous Secondary Cache SRAM Module
General Description
The SM364TCSMB3UI15 is a high performance, 256
Kilobyte synchronous secondary cache SRAM module for
use with Intel Triton Chipset. It is organized as 32K
words by 64 bits, in a 160-pin, dual readout, leadless,
double-in-line memory module (DIMM) package.
The module utilizes two CMOS 32Kx32 static RAMs for
data and two 8Kx8 static RAM for tag in surface mount
packages on an epoxy laminate substrate. Each device is
accompanied by decoupling capacitors for improved noise
immunity.
Control lines provided are such that byte write control is
possible.
