Notes:
1. Address format A14-A0 (Hex), Addresses A18-A15 can be VIL or VIH, but no other value, for the Command
sequence.
2. DQ15-DQ8 can be VIL or VIH, but no other value, for the Command sequence.
3. WA = Program word address.
4. SAX for Sector-Erase; uses A18-A11 address lines.
BAX for Block-Erase; uses A18-A15 address lines.
5. The device does not remain in Software Product ID mode if powered down.
6. Both Software ID Exit operations are equivalent.
7. Refer to Figure 9 for more information.
