PARALLEL NON-VOLATILE RAM
S-22 Series
The S-22 Series is a non-volatile CMOS RAM, composed of a CMOS
static RAM and a non-volatile electrically erasable and programmable
memory (E
2
PROM) to backup the SRAM. The organization is 256-
word
×
4-bit (total 1K bits) for the S-22H12 and the S-22S12, and 64-
word
×
4-bit (total 256 bits) for the S-22H10 and the S-22S10.
