STK22C48  
2Kx8 AutoStore nvSRAM  
DESCRIPTION  
FEATURES  
• 25, 45 ns Read Access & R/W Cycle Times  
The Simtek STK22C48 is a 16Kb fast static RAM with  
a nonvolatile Quantum Trap storage element included  
with each memory cell.  
• Unlimited Read/Write Endurance  
• Automatic Non-Volatile STORE on Power Loss  
• Non-Volatile STORE Under Hardware Control  
• Automatic RECALL to SRAM on Power Up  
• Unlimited RECALL Cycles  
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.  
• 1 Million STORE Cycles  
• 100-Year Non-volatile Data Retention  
• Single 5V + 10% Operation  
• Commercial, Industrial, and Military  
Temperatures  
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.  
• 28-Pin 300 mil SOIC or 330 mil SOIC (RoHS-  
Compliant)
