Abstract
In some implementations, a memory apparatus may identify a retirement condition for a block of one or more blocks of the memory apparatus, the retirement condition based on an average maintenance metric of the one or more blocks. The memory apparatus may retire the block based on a determination that a maintenance metric of the block satisfies the retirement condition.
Claims23
A memory device, comprising:
- one or more components configured to:
- identify a retirement condition for a block of one or more blocks of the memory device, the retirement condition based on an average maintenance metric of the one or more blocks;
- and
- retire the block based on a determination that a maintenance metric of the block satisfies the retirement condition.
1 more element
A method, comprising:
- identifying a retirement condition for a block of one or more blocks of a memory apparatus, the retirement condition based on an average degradation metric of the one or more blocks;
- and
- retiring the block based on determining that a degradation metric of the block satisfies the retirement condition.
A memory device, comprising:
- one or more components configured to:
- identify a retirement condition for a block of one or more blocks of the memory device;
- and
- retire the block based on a determination that a refresh metric of the block satisfies the retirement condition, the refresh metric based on a quantity of refresh operations performed on the block.

A memory device, comprising:
- one or more components configured to:
- identify a retirement condition for a block of one or more blocks of the memory device;
- and
- retire the block based on a determination that an error control metric of the block satisfies the retirement condition, the error control metric based on a quantity of error control operations performed on the block.
