Unusable Sector
Initially, the HN29W25611T includes unusable sectors. The unusable sectors must be distinguished from the
usable sectors by the system as follows.
1. Check the partial invalid sectors in the devices on the system. The usable sectors were programmed the
following data. Refer to the flowchart “Indication of unusable sectors”.
Initial Data of Usable Sectors
Column address
0H to 81FH
820H
821H
