NOTE :
1. This device may include invalid blocks when first shipped. Additional invalid blocks may develop while being used. The number of valid blocks is pre-
sented with both cases of invalid blocks considered. Invalid blocks are defined as blocks that contain one or more bad bits. Do not erase or program
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 fully guaranteed to be a valid block, does not require Error Correction.
3. The 2nd and 3rd blocks are good upon shipping.
