SPEC may change after device evaluation.
Characteristic of the flash memory. For the characteristic when a dedicated flash memory programmer,
PG-FP4, is used and the rewrite time during self programming,
The prewrite time before erasure and the erase verify time (writeback time) are not included.
When a product is first written after shipment, “erase → write” and “write only” are both taken as one
rewrite.
