M48Z2M1Y General 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 standard 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.
