... The AutoStorePlus™ STK16C68 is a fast SRAM that does not lose its data on power-down. The data is preserved in integral QuantumTrap™ Nonvolatile Elements while power is unavailable. The nonvolatility of the STK16C68 does not require any system intervention or support: AutoStore- Plus™ on power-down and automatic RECALL on power-up guarantee data integrity without the use of batteries ...
