Nonvolatile Static RAM
DESCRIPTION
The Xicor X20C04 is a 512 x 8 NOVRAM featuring a
static RAM overlaid bit-for-bit with a nonvolatile electri-
cally erasable PROM (E
2
PROM). The X20C04 is fabri-
cated with advanced CMOS floating gate technology to
achieve low power and wide power-supply margin. The
X20C04 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.
