TOSHIBA MOS MEMORY PRODUCT
8,192 WORD X 9 BIT STATIC RAM
N-CHANNEL SILICON GATE MOS
TMM2089p-35, TMM2089P-45
TMM2089p-55
\DESCRIPTION\
The THM2089P is a 73,723 bits high speed N-channel silicon gate MOS static random
access memory organized as ~,192 words by 9 bits and operates from a single 5-volt
supply. The T~lli2089P is features an automatic stand-by mode when deselect by CSI
signal. Thus the TMM2089P is suitable for use in cache memory and high speed storage.
TheTMl'12089P has nine I/O terminals, therefore it is most suitable for MEMORY SYSTEM
with Parity bit. The TMM2089P is offered in a 28 pin standard plastic dual in-line
package with 0.3 inch width for high density assembly.
