8-bit asynchronous silicon gate CMOS
static RAMs. These devices use a 6-transistor full CMOS
memory cell, and feature low-voltage operation, low
current drain, and an ultralow standby current. They
provide two control signal inputs: an OE input for high-
speed access and a chip select (CE) input for device
selection and low power operating mode. This makes
these devices optimal for systems that require low power
or battery backup, and they allow memory to be expanded
easily. Their ultralow standby current allows capacitor-
based backup to be used as well. Since they support 3-V
operation, they are appropriate for use in portable systems
that operate from batteries.
