TOSHIBA MOS MEMORY PRODUCT
8,192 WORD X 9 BIT STATIC RAM
N-CHANNEL SILICON GATE MOS
TM M2089C-35
TMM2089C-45
TMM2089C-55
DESCRIPTION
The TMM2089C is a 73,728 bits high speed N-
channel silicon gate MOS static random access
memory organized as 8,192 words by 9 bits and
operates from a single 5-volt supply. The
TMM2089C is features an automatic stand-by mode
when deselect by cST signal. Thus the TMM2089C
PRELIMINARY
is suitable for use in cache memory and high speed
storage. The TMM2089C has nine I/O terminals,
therefore it is most suitable for MEMORY SYSTEM
with Parity bit. The TMM2089C is offered is a 28 prn
standard ceramic dual in-line package with 0.3 inch
width for high density assembly.
