High Speed AUTOSTORE NOVRAM
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
2
PROM) and the
AUTOSTORE feature which automatically saves the
RAM contents to E
2
PROM at power-down. The X20C16
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-
ible JEDEC approved pinout for byte-wide memories,
for 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 10
μ
s or
less. An automatic array recall operation reloads the
contents of the E
2
PROM into RAM upon power-up.
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.
