SRAM SUMMARY DESCRIPTION
The SRAM is a 4Mbit asynchronous random ac-
cess memory which features a super low voltage
operation and low current consumption with an ac-
cess time of 70 ns under all conditions. The mem-

ory operations can be performed using a single
low voltage supply, 2.7V to 3.3V, which is the
same as the Flash voltage supply.
