(4)

1. Data based on characterization results, not tested in production.

2. Conforming to JEDEC JESD22a117

3. The physical granularity of the memory is 4 bytes, so cycling is performed on 4 bytes even when a write/erase operation

addresses a single byte.

4. Data based on characterization performed on the whole data memory.
