X20C04

The Xicor X20C04 is a 512 x 8 NOVRAM featuring a static RAM overlaid bit-for-bit with a nonvolatile electrically erasable PROM (E²PROM). The X20C04 is fabricated with advanced CMOS floating gate technology to achieve low power and wide power-supply margin. The X20C04 features the JEDEC approved pinout for bytewide memories, compatible with industry standard RAMs,ROMs, EPROMs, and E²PROMs.

The NOVRAM design allows data to be easily transferred from RAM to E²PROM (store) and E²PROM to RAM (recall). The store operation of X20C04 is completed in 5ms or less and the recall operation is completed in 5ms 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.
