DESCRIPTION
 The Simtek STK14EC16 is a 4MB 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 storage cells when power loss is detected (the STOREoperation).
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 highest performance, most reliable non-volatile memory available.
