NOTE :
1. The device may include initial invalid blocks when first shipped. Additional invalid blocks may develop while being used. The number of valid blocks is
presented 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 initial invalid blocks.
2. The 1st block, which is placed on 00h block address, is guaranteed to be a valid block at the time of shipment.
3. The number of valid block is on the basis of single plane operations, and this may be decreased with two plane operations.
* : Each K9G4G08U0A chip in the K9L8G08U1A has Maximun 50 invalid blocks.
