About write operation of nvSRAM (CY14B101NA-ZS25XI)

[MAO]

In the Write operation, if / WE is asserted and then negated earlier than the Min value of tpwe,

Is the content of SRAM at the address undefined? Or does the previous value remain?

If it is undefined, if the power is turned off and then turned on in that state, the SRAM → nvSRAM store operation (@power off) will be performed as an indefinite value.

Does nvSRAM → SRAM recall operation (@ power ON) and nvSRAM operates with an undefined value?

Hi @MAO ,

If the WE is negated before the tPWE timing requirement then it can lead to data corruption at that particular address.

So in that case it is recommended to write the correct value again into the address location as the data reliability cannot be guaranteed in such cases. 

Thanks,

Pradipta.
