DESCRIPTION
The Simtek STK15C88 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.
PowerStore nvSRAM products depend on the intrin-
sic system capacitance to maintain system power
long enough for an automatic store on power loss. If
the power ramp from 5 volts to 3.6 volts is faster
than 10 ms, consider our 14C88 or 16C88 for more
reliable operation.
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.
