FEATURES  
DESCRIPTION  
• 25ns, 35ns and 45ns Access Times  
The Simtek STK11C88 is a fast static RAM with a  
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), or from Nonvolatile Elements  
to SRAM (the RECALL operation), are initiated using  
a software sequence. Data transfers from the Non-  
volatile Elements to the SRAM (the RECALL opera-  
tion) also occur upon restoration of power.  
STORE to Nonvolatile Elements Initiated by  
Software  
RECALL to SRAM Initiated by Software or  
Power Restore  
• 10mA Typical ICC at 200ns Cycle Time  
• Unlimited READ, WRITE and RECALL Cycles  
• 1,000,000 STORE Cycles to Nonvolatile Ele-  
ments (Commercial/Industrial)  
• 100-Year Data Retention in Nonvolatile Ele-  
ments (Commercial/Industrial)  
The STK11C88 is pin-compatible with industry-  
standard SRAMs.  
• Single 5V + 10% Operation  
• Commercial and Industrial Temperatures  
• 28-Pin PDIP and SOIC Packages
