Will NVSRAM's STORE and RECALL processes work after the STORE process exceeds 1 million times?
What happens if the STORE and RECALL processes do not work?

Hi,
The nvSRAM store cycles are guaranteed for 1 million time usage. After this usage the the store operation might work or might not work but we cannot guarantee any performance of the device store operation after the datasheet listed usage of 1 million. Recall operation does not have any limitations you can use it infinite number of times in theory.
Each nvSRAM memory cell is a composition of two cell actually. One is a volatile SRAM cell from where we read and write to the memory and the other is the SONOS cell which is non volatile section. Since write operations to any non volatile memory are limited so there is a limitation on the store operation. There is limitation on reading from the non volatile section so restrictions on recall operation. If your store operation is not working you will not be able to use the non volatile section of the memory or in theory your memory will be reduced to a simple volatile SRAM memory.
Thanks,
Pradipta.
