... The STK14CA8 nvSRAM is made up of two func- tional components paired in the same physical cell. These are the SRAM memory cell and a nonvolatile QuantumTrap cell. The SRAM memory cell operates like a standard fast static RAM. Data in the SRAM can be transferred to the nonvolatile cell (the STORE operation), or from the nonvolatile cell to SRAM (the RECALL operation) ...

... SRAM READ and WRITE operations that are in progress when HSB is driven low by any means are given time to complete before the STORE operation is initiated. After HSB goes low, the STK14CA8 will continue to allow SRAM operations for t ing t , multiple SRAM READ operations may DELAY take place ...

... STORE and WRITE operations. The low- voltage condition is detected when V If the STK14CA8 WRITE mode (both E and W low) at power-up, after a RECALL, or after a STORE, the WRITE will be inhibited until a negative transition detected. This protects against inadvertent writes during power up or brown out conditions ...
