High Speed AUTOSTORE™ NOVRAM

FEATURES

DESCRIPTION

• 24-Pin Standard SRAM DIP Pinout

• Fast Access Time: 35ns, 45ns, 55ns

• High Reliability

TheXicorX20C17isa2Kx8NOVRAMfeaturingahigh-

speed static RAM overlaid bit-for-bit with a nonvolatile

electrically erasable PROM (E²PROM) and the

AUTOSTORE feature which automatically saves the

RAMcontentstoE²PROMatpower-down. TheX20C17

isfabricatedwithadvancedCMOSfloatinggatetechnol-

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.

—Endurance: 1,000,000 Nonvolatile Store

Operations

—Retention: 100 Years Minimum

• AUTOSTORE™ NOVRAM

—Automatically Stores SRAM Data Into the

E²PROM Array When V_CCLow Threshold is

Detected

—E²PROM Data Automatically Recalled Into

RAM Upon Power-up

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 2.5ms

or less. An automatic array recall operation reloads the

contents of the E²PROM into RAM upon power-up.

• Low Power CMOS

—Standby: 250µA

• Infinite E²PROM Array Recall, and RAM Read

and Write Cycles

Xicor NOVRAMS are designed for unlimited write

operations to RAM, either from the host or recalls from

E²PROM, andaminimum1,000,000storeoperationsto

the E²PROM. Data retention is specified to be greater

than 100 years.
