262144-BIT (32768-WORD BY 8-BIT) CMOS STATIC RAM
DESCRIPTION
The M5M5256DFP,VP is 262,144-bit CMOS static RAMs
organized as 32,768-words by 8-bits which is f abricated using
high-perf ormance 3 poly silicon CMOS technology . The use of
resistiv e load NMOS cells and CMOS periphery results in a high
density and low power static RAM. Stand-by current is small
enough f or battery back-up application. It is ideal f or the memory
sy stems which require simple interf ace.
Especially the M5M5256DVP are packaged in a 28-pin thin small
outline package.
