DESCRIPTION
The M48Z2M1/2M1Y ZEROPOWER
RAM is a
non-volatile 16,777,216 bit Static RAM organized
as 2,097,152 words by 8 bits. The device combines
two internal lithium batteries, CMOS SRAMs and a
control circuit in a plastic 36 pin DIP long Module.
The ZEROPOWER RAM replaces industry stand-
ard SRAMs. It provides the nonvolatility of PROMs
without any requirement for special write timing or
limitations on the number of writes that can be
performed.
