FEATURES

DESCRIPTION

The Xicor X20C17 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 X20C17

is fabricated with advanced CMOS floating gate technol-

ogy to achieve high speed with low power and wide

power-supply margin. The X20C17 features a compat-

ible JEDEC approved byte-wide memory pinout for

industry standard SRAMs.

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 2.5ms

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.
