STK14C88-3  
32K x 8 AutoStore™ nvSRAM  
QuantumTrap™ CMOS  
Nonvolatile Static RAM  
FEATURES  
DESCRIPTION  
The Simtek STK14C88-3 is a fast static RAM with a  
• 35ns, 45ns and 55ns Access Times  
• “Hands-off” Automatic STORE with External  
nonvolatile element incorporated in each static  
memory cell. The SRAM can be read and written an  
unlimited number of times, while independent, non-  
volatile data resides in nonvolatile elements. Data  
transfers from the SRAM to the nonvolatile elements  
(the STORE operation) can take place automatically  
on power down. A 68µF or larger capacitor tied from  
VCAP to ground guarantees the STORE operation,  
regardless of power-down slew rate or loss of power  
from “hot swapping”. Transfers from the nonvolatile  
elements to the SRAM (the RECALL operation) take  
place automatically on restoration of power. Initia-  
tion of STORE and RECALL cycles can also be soft-  
ware controlled by entering specific read  
sequences. A hardware STORE may be initiated with  
the HSB pin.

• 100-Year Data Retention in nonvolatile ele-  
ments (Commercial/Industrial)  
• Single 3.3V + 0.3V Operation  
• Commercial and Industrial Temperatures
