Abstract
A first analysis of each respective die of a multi-die memory device is performed. An equation to determine a respective temperature compensation (tempco) value for each respective die based on a number of program erase cycles (PECs) of the respective die based on the first analysis s determined. The equation for use in processing memory access requests directed to the respective die is stored. Whether to update the equation directed to the respective die based on a second analysis of the respective die is determined.
Claims20
A method comprising:
- identifying a set of parameters associated with a fitting equation for use in processing memory access requests directed to a die of the plurality of dies;
- receiving a plurality of temperature compensation (tempco) values for each die of the plurality of dies;
- and
- updating, based the pluralities of tempco values and an optimization method, the set of parameters.
A system comprising:
- a memory device;
- and
- a processing device, operatively coupled to the memory device, the processing device to perform operations comprising:
- identifying a set of parameters associated with a fitting equation for use in processing memory access requests directed to a die of the plurality of dies;
- receiving a plurality of temperature compensation (tempco) values for each die of the plurality of dies;
- and
- updating, based the pluralities of tempco values and an optimization method, the set of parameters.
A non-transitory computer readable storage medium including instructions that, when executed by a processing device, cause the processing device to perform a method comprising:
- identifying a set of parameters associated with a fitting equation for use in processing memory access requests directed to a die of the plurality of dies;
- receiving a plurality of temperature compensation (tempco) values for each die of the plurality of dies;
- and
- updating, based the pluralities of tempco values and an optimization method, the set of parameters.
