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.
Claims20
A memory sub-system comprising:
- a memory device;
- and
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- detecting a failed erase operation at a memory block of the memory device;
- based on detecting the failed erase operation at the memory block, destroying data on the memory block using a data destruction pulse that corrupts the data on the memory block;
- verifying the data on the memory block is destroyed;
- and
- providing a passing data destruction status for the memory block based on verifying the data on the memory block is destroyed.
method comprising:
- detecting a failed erase operation at a memory block of a memory device;
- based on detecting the failed erase operation at the memory block, destroying data on the memory block using a data destruction pulse that corrupts the data on the memory block;
- verifying the data on the memory block is destroyed;
- and
- providing a passing data destruction status for the memory block based on verifying the data on the memory block is destroyed.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, configure the processing device to perform operations comprising:
- detecting a failed erase operation at a memory block of the memory device;
- based on detecting the failed erase operation at the memory block, destroying data on the memory block using a data destruction pulse that corrupts the data on the memory block;
- verifying the data on the memory block is destroyed;
- and
- providing a passing data destruction status for the memory block based on verifying the data on the memory block is destroyed.
