Nonvolatile Static RAM  
Obsolete - Not Recommend for new Designs  
DESCRIPTION  
FEATURES  
The Simtek STK10C68 is a fast static RAM with a nonvol-  
atile element incorporated in each static memory cell. The  
SRAM can be read and written an unlimited number of  
times, while independent nonvolatile data resides in Non-  
volatile Elements. Data may easily be transferred from  
the SRAM to the Nonvolatile Elements (the STORE oper-  
ation), or from the Nonvolatile Elements to the SRAM  
(the RECALL operation), using the NE pin. Transfers  
from the Nonvolatile Elements to the SRAM (the  
RECALL operation) also take place automatically on  
restoration of power. The STK10C68 combines the high  
performance and ease of use of a fast SRAM with nonvol-  
atile data integrity.  
• 25ns, 35ns, 45ns and 55ns Access Times  
STORE to Nonvolatile Elements Initiated by  
Hardware  
RECALL to SRAM Initiated by Hardware or  
Power Restore  
• Automatic STORE Timing  
• 10mA Typical ICC at 200ns Cycle Time  
• Unlimited READ, WRITE and RECALL Cycles  
• 1,000,000 STORE Cycles to Nonvolatile Ele-  
ments (Industrial/Commercial)  
• 100-Year Data Retention (Industrial/Commer-  
cial)  
• Commercial, Industrial and Military Tempera-  
tures  
• 28-Pin DIP, SOIC and LCC Packages  
The STK10C68 features industry-standard pinout for non-  
volatile RAMs. MIL-STD-883 and Standard Military Draw-  
ing (SMD #5962-93056) devices are available.
