DESCRIPTION
The Xicor X20C05 is a 512 x 8 NOVRAM featuring a
high-speed static RAM overlaid bit-for-bit with a non-
volatile electrically erasable PROM (E
2
PROM). The
X20C05 is fabricated with advanced CMOS floating
gate technology to achieve high speed with low power
and wide power-supply margin. The X20C05 features
the JEDEC approved pinout for byte-wide memories,
compatible with industry standard RAMs, ROMs,
EPROMs, and E
2
PROMs.
The NOVRAM design allows data to be easily trans-
ferred from RAM to E
2
PROM (store) and E
2
PROM to
RAM (recall). The store operation is completed in 5ms or
less and the recall operation is completed in 5
μ
s or less.
Xicor NOVRAMS are designed for unlimited write
operations to RAM, either from the host or recalls from
E
2
PROM, and a minimum 1,000,000 store operations to
the E
2
PROM. Data retention is specified to be greater
than 100 years.
