Abstract
A memory system includes a memory device and a processing device coupled to the memory device. The processing device receives a plurality of codewords; determines that one or more codewords of the plurality of codewords are corrupt; selects a first read voltage associated with the one or more codewords, such that the first read voltage is based on a second read voltage utilized for reading the one or more codewords in a previous read operation; and applies the first read voltage to a set of memory cells storing the one or more corrupted codewords.
Claims20
A system comprising:
- a memory device;
- a processing device, operatively coupled to the memory device, the processing device configured to:
- receive a plurality of codewords;
- determine that one or more codewords of the plurality of codewords are corrupt;
- select a first read voltage associated with the one or more codewords, wherein the first read voltage is based on a second read voltage utilized for reading the one or more codewords in a previous read operation;
- and
- apply the first read voltage to a set of memory cells storing the one or more codewords.
A method, comprising:
- receiving, by a processing device, a plurality of codewords;
- determining that one or more codewords of the plurality of codewords are corrupt;
- selecting a first read voltage associated with the one or more codewords, wherein the first read voltage is based on a second read voltage utilized for reading the one or more codewords in a previous read operation;
- and
- applying the first read voltage to a set of memory cells storing the one or more codewords.
A non-transitory computer-readable storage medium comprising executable instructions, which when executed by a processing device, cause the processing device to:
- receive a plurality of codewords;
- determine that one or more codewords of the plurality of codewords are corrupt;
- select a first read voltage associated with the one or more codewords, wherein the first read voltage is based on a second read voltage utilized for reading the one or more codewords in a previous read operation;
- and
- apply the first read voltage to a set of memory cells storing the one or more codewords.
