Abstract
A processing device in a memory system receives a data access request identifying a memory cell in a first segment of the memory system comprising at least a portion of at least one memory device. The processing device determines a temperature difference between a current temperature associated with the memory cell and a baseline temperature of the memory system and identifies a temperature compensation value specific to the first segment of the memory system, the temperature compensation value corresponding to the temperature difference. The processing device adjusts, based on an amount represented by the temperature compensation value, an access control voltage applied to the memory cell.
Claims20
A memory system comprising:
- at least one memory device;
- and
- a processing device, operatively coupled with the at least one memory device, the processing device to:
- receive a data access request identifying a memory cell in a first segment of the memory system comprising at least a portion of the at least one memory device;
- determine a temperature difference between a current temperature associated with the memory cell and a baseline temperature of the memory system;
- identify a temperature compensation value specific to the first segment of the memory system, the temperature compensation value corresponding to the temperature difference;
- and
- adjust, based on an amount represented by the temperature compensation value, an access control voltage applied to the memory cell.
A method comprising:
- receiving a data access request identifying a memory cell in a first segment of a memory system comprising at least a portion of at least one memory device;
- determining a temperature difference between a current temperature associated with the memory cell and a baseline temperature of the memory system;
- identifying, by a processing device, a temperature compensation value specific to the first segment of the memory system, the temperature compensation value corresponding to the temperature difference;
- and
- adjusting, based on an amount represented by the temperature compensation value, an access control voltage applied to the memory cell.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:
- receive a data access request identifying a memory cell in a first segment of a memory system comprising at least a portion of at least one memory device;
- determine a temperature difference between a current temperature associated with the memory cell and a baseline temperature of the memory system;
- identify a temperature compensation value specific to the first segment of the memory system, the temperature compensation value corresponding to the temperature difference;
- and
- adjust, based on an amount represented by the temperature compensation value, an access control voltage applied to the memory cell.
