Abstract
A first operating characteristic and a second operating characteristic of a memory sub-system are determined. A write-to-read delay time is set in view of the first operating characteristic and the second operating characteristic. A read operation associated with a memory unit is executed following a period of at least the write-to-read delay time from a time of an execution of a write operation associated with the memory unit.
Claims20
A method comprising:
- determining a first operating characteristic of a memory sub-system;
- determining a second operating characteristic of the memory sub-system;
- setting a write-to-read (W2R) delay time in view of the first operating characteristic and the second operating characteristic;
- and
- executing, by a processing device, a read operation associated with a memory unit of the memory sub-system, following a period of at least the W2R delay time from a time of an execution of a write operation associated with the memory unit.
A non-transitory computer readable medium comprising instructions, which when executed by a processing device, cause the processing device to perform operations comprising:
- determining a current cycle count associated with a memory sub-system;
- comparing the current cycle count to a set of cycle count threshold levels to determine a current lifecycle stage of the memory sub-system;
- measuring a temperature associated with the memory sub-system;
- comparing the temperature to a set of temperature levels to determine a current temperature level of the memory sub-system;
- and
- identifying a W2R delay time corresponding to the current lifecycle stage and the current temperature level.
A system comprising:
- a memory component;
- and
- a processing device, operatively coupled with the memory component, to:
- determine a first operating characteristic of a memory sub-system;
- determine a second operating characteristic of the memory sub-system;
- set a write-to-read (W2R) delay time in view of the first operating characteristic and the second operating characteristic;
- and
- execute a read operation associated with a memory unit following a period of at least the W2R delay time from a time of an execution of a write operation associated with the memory unit.
