The Simtek STK14D88 is a fast static RAM with a  
nonvolatile element in each memory cell. The  
embedded  
nonvolatile  
elements  
incorporate  
Simtek’s QuantumTraptechnology producing the  
world’s most reliable nonvolatile memory. The  
SRAM provides unlimited read and write cycles,  
while independent, nonvolatile data resides in the  
highly reliable QuantumTrapTM cell. Data transfers  
from the SRAM to the nonvolatile elements (the  
STORE operation) takes place automatically at  
power down. On power up, data is restored to the  
SRAM (the RECALL operation) from the nonvolatile  
memory. Both the STORE and RECALL operations  
are also available under software control.
