VALID BLOCK
NOTE
:
1. The KM29W32000 may or may not include bad blocks. Bad blocks are defined as blocks that contain one or more bad bits. Do not try to access these
bad blocks for program and erase. The Minimum valid blocks are guaranteed for 10 years data retention or 1M program erase cycling. (Refer to the
attached technical notes)
2. The 1st block, which is placed on 00h block address, is guaranteed to be a good block
