KM29U128T, KM29U128IT
VALID BLOCK
NOTE :
1. The KM29U128 may include invalid blocks. Invalid blocks are defined as blocks that contain one or more bad bits. Do not try to access these invalid
2. The 1st block, which is placed on 00h block address, is guaranteed to be a valid block
CAPACITANCE
NOTE : Capacitance is periodically sampled and not 100% tested.
MODE SELECTION
NOTE : 1. X can be V
