PBB Program Operation
9.2.2
Erasing PPB
The All PPB Erase command is used to erase all the PPBs in bulk. There are no means for individually
erasing a specific PPB. The first three cycles of the PPB Erase command are standard unlock cycles. The
fourth cycle executes the erase pulse to all the PBBs. The user must wait either 20ms or until DQ6 stops
toggling before executing the fifth cycle, which is the read verify portion of the PPB Erase Command. The
sixth cycle outputs the status of the PPB Erase operation.
In the event that the erase PPB operation was not successful, the user can loop directly to the fourth cycle of
the All PPB Erase Command to perform the erase pulse and read verification again. After four unsuccessful
loops through the erase pulse and read verification cycles, the PPB erasing operation should be considered a
failure.
Note
All PPB must be preprogrammed prior to issuing the All PPB Erase Command.
