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 E
2
PROM 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 E
2
PROM) is completed in 5ms or less
and a recall operation (E
2
PROM data to RAM) is com-
pleted in 2
μ
s or less.
Xicor NOVRAMs are designed for unlimited write opera-
tions to RAM, either from the host or recalls from
E
2
PROM and a minimum 1,000,000 store operations.
Inherent data retention is specified to be greater than
100 years.
