X20C16

The Xicor X20C16 is a 2K x 8 NOVRAM featuring a highspeed static RAM overlaid bit-for-bit with a nonvolatile electrically erasable PROM (E²PROM) and the AUTOSTORE feature which automatically saves the RAM contents to E²PROM at power-down. The X20C16 is fabricated with advanced CMOS floating gate technology to achieve high speed with low power and wide power-supply margin. The X20C16 features a compatible JEDEC approved pinout for byte-wide memories,for 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 X20C16 is completed in 5ms or less and the recall operation is completed in 10ms or less. An automatic array recall operation reloads the contents of the E²PROM into RAM upon power-up.

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
