DESCRIPTION

The Xicor X24C44 is a serial 256 bit NOVRAM featuring

a static RAM configured 16 x 16, overlaid bit-by-bit with

a nonvolatile E2PROM array. The X24C44 is fabricated

with Xicor’s Advanced CMOS Floating Gate technology.

The Xicor NOVRAM design allows data to be transferred

between the two memory arrays by means of software

commands or external hardware inputs. A store opera-

tion (RAM data to E2PROM) is completed in 5ms or less

and a recall operation (E2PROM data to RAM) is com-

pleted in 2

µs or less.

Xicor NOVRAMs are designed for unlimited write opera-

tions to RAM, either from the host or recalls from

E2PROM and a minimum 1,000,000 store operations.

Inherent data retention is specified to be greater than

100 years.
