DESCRIPTION

The Xicor X20C16 is a 2K x 8 NOVRAM featuring a high-

speed static RAM overlaid bit-for-bit with a nonvolatile

electrically erasable PROM (E

AUTOSTORE feature which automatically saves the

is fabricated with advanced CMOS floating gate technol-

ogy to achieve high speed with low power and wide

power-supply margin. The X20C16 features a compat-

for industry standard RAMs, ROMs, EPROMs, and

The NOVRAM design allows data to be easily trans-

ferred from RAM to E
