... Cypress Semiconductor Corporation Document Number: 001-06727 Rev Kbit ( nvSRAM Functional Description The Cypress CY22E016L is a fast static RAM with a nonvol- atile element incorporated in each static memory cell. The SRAM is read and written an infinite number of times, while independent, nonvolatile data resides in nonvolatile elements. ...

... STORE, the WRITE is inhibited until a negative transition detected. This protects against inadvertent writes during power up or brown out conditions. Noise Considerations The CY22E016L is a high speed memory. It must have a high frequency bypass capacitor of approximately 0.1 µF connected between V and possible ...

... The STORE function is disabled by holding HSB HIGH with a driver capable of sourcing because it has to overpower the internal pull down device. The device drives HSB low for the onset of a STORE.
