US 2024/0192875 A1 · REMAPPING BAD BLOCKS IN A MEMORY SUB-SYSTEM

Abstract

A system includes a memory device having a plurality of memory planes and a processing device operatively coupled with the memory device. The processing device to is perform operations including identifying a first block stripe of the memory device. The first block stripe includes a first plurality of blocks arranged across the plurality of memory planes. The operations further include determining that the first plurality of blocks of the first block stripe has greater than a threshold number of blocks associated with an error condition. Responsive to determining that the first plurality of blocks has greater than the threshold number of blocks associated with the error condition, the operations further include mapping a block of the first plurality of blocks associated with the error condition to a second block stripe including a second plurality of blocks having fewer than the threshold number of blocks associated with the error condition.

A method comprising:

identifying a first block stripe of a memory device, wherein the first block stripe comprises a first plurality of blocks arranged across a plurality of memory planes of the memory device;
determining that the first plurality of blocks of the first block stripe has greater than a threshold number of blocks associated with an error condition;
and
responsive to determining that the first plurality of blocks has greater than the threshold number of blocks associated with the error condition, mapping a first block of the first plurality of blocks associated with the error condition to a second block stripe comprising a second plurality of blocks having fewer than the threshold number of blocks associated with the error condition.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

identifying a first block stripe of a memory device, wherein the first block stripe comprises a first plurality of blocks arranged across a plurality of memory planes of the memory device;
determining that the first plurality of blocks of the first block stripe has greater than a threshold number of blocks associated with an error condition;
and
responsive to determining that the first plurality of blocks has greater than the threshold number of blocks associated with the error condition, mapping a first block of the first plurality of blocks associated with the error condition to a second block stripe comprising a second plurality of blocks having fewer than the threshold number of blocks associated with the error condition.
