Abstract
A failed erase operation is detected at a memory block of a memory device. Based on detecting the failed erase operation at the memory block, data on the memory block is destroyed using a data destruction algorithm that corrupts data stored by one or more cells of the block. The data on the memory block is verified to be destroyed. A passing data destruction status for the memory block is provided based on verifying the data on the memory block is destroyed.
