NOTE :
1. The 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 pro-
gram factory-marked bad blocks. Refer to the attached technical notes for 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.
* : Each K9K2GXXX0M chip in the K9W4GXXU1M has Maximum 40 invalid blocks.
