X20C16

High Speed AUTOSTORE™ NOVRAM

2K x 8 Bit

FEATURES

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

PROM) and the

AUTOSTORE feature which automatically saves the

RAM contents to E

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

PROMs.

The NOVRAM design allows data to be easily trans-

ferred from RAM to E

PROM (store) and E

PROM to

RAM (recall). The store operation is completed in 5ms or

less and the recall operation is completed in 10µs or

less. An automatic array recall operation reloads the

contents of the E

PROM into RAM upon power-up.

Xicor NOVRAMS are designed for unlimited write

operations to RAM, either from the host or recalls from

PROM, and a minimum 1,000,000 store operations to

the E

PROM. Data retention is specified to be greater

than 100 years.
