VALID BLOCK

NOTE :

1. The

sented with both cases of invalid blocks considered. Invalid blocks are defined as blocks that contain one or more bad bits

factory-marked bad blocks. Refer to the attached technical notes for a appropriate management of invalid blocks.

2. The 1st block, which is placed on 00h block address, is guaranteed to be a valid block, does not require Error Correction up to 1K program/erase

cycles.

3. Minimum 502 valid blocks are guaranteed for each contiguous 64Mb memory space.
