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 (E2PROM). 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 E2PROMs.
The NOVRAM design allows data to be easily trans-
ferred from RAM to E2PROM (store) and E2PROM to
RAM (recall). The store operation is completed in 5ms or
less and the recall operation is completed in 5µs or less.
Xicor NOVRAMS are designed for unlimited write
operations to RAM, either from the host or recalls from
E2PROM, and a minimum 1,000,000 store operations to
the E2PROM. Data retention is specified to be greater
than 100 years.
