VALID BLOCK
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 K9K4G08U0M chip in the K9W8G08U1M has Maximum 80 invalid blocks.
