DESCRIPTION
STK11C88
32Kx8 SoftStore nvSRAM
The Simtek STK11C88 is a 256Kb fast static RAM
with a non-volatile Quantum Trap storage element
included with each memory cell.
The SRAM provides the fast access & cycle times,
ease of use and unlimited read & write endurance of
a normal SRAM.
Data transfers under software control to the non-vol-
atile storage cell (the STORE operation). On power
up, data is automatically restored to the SRAM (the
RECALL operation). RECALL operations are also
available under software control.
The Simtek nvSRAM is the first monolithic non-
volatile memory to offer unlimited writes and reads.
It is the highest performance, most reliable non-
volatile memory available.
