1 / 10 page March 2006 1 Document Control # ML0013 rev 0.2 STK11C88-3 32K x 8 nvSRAM 3.3V QuantumTrap™ CMOS Nonvolatile Static RAM Obsolete - Not Recommend for new Deisgns FEATURES • 35, 45ns and 55ns Access Times • STORE to Nonvolatile Elements Initiated by Software • RECALL to SRAM Initiated by Software or Power Restore • 10 mA Typical Icc at 200 nsec Cycle Time • Unlimited READ, WRITE and RECALL Cycles • 1,000,000 STORE Cycles to Nonvolatile Ele- ments • 100-Year Data Retention in Nonvolatile Ele- ments • Single 3.3V+ 0.3V Operation • Commercial and Industrial Temperatures • 28-Pin DIP and SOIC Packages DESCRIPTION The Simtek STK11C88-3 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 Nonvol- atile Elements to the SRAM (the RECALL operation) also occur upon restoration of power.
