DESCRIPTION
The Simtek STK14C88-3 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 automatically to the non-volatile stor-
age cells when power loss is detected (the STORE
operation). On power up, data is automatically
restored to the SRAM (the RECALL operation). Both
STORE and RECALL operations are also available
under software control.
The Simtek nvSRAM is the first monolithic non-vola-
tile memory to offer unlimited writes and reads. It is
the highest performance, most reliable non-volatile
memory available.
