Abstract
A trigger rate associated with a scan operation of a set of memory pages of a data block is identified. The trigger rate is compared to a threshold rate to determine that a condition is satisfied. In response to satisfying the condition, a refresh operation is executed on the set of memory pages of the data block.
Claims20
A method comprising:
- executing a scan operation to identify a trigger rate associated with a set of memory pages of a data block of a memory device, wherein the trigger rate represents a number of the set of memory pages that fail an error management operation;
- comparing the trigger rate to a threshold trigger rate to determine that a condition is satisfied;
- and
- in response to satisfying the condition, executing, by a processing device, a refresh operation on the set of memory pages of the data block.

A system comprising:
- a memory device;
- and
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- executing a scan operation to identify a trigger rate associated with a set of memory pages of a data block of the memory device, wherein the trigger rate represents a number of the set of memory pages that fail an error management operation;
- comparing the trigger rate to a threshold trigger rate to determine that a condition is satisfied;
- and
- in response to satisfying the condition, executing a refresh operation on the set of memory pages of the data block.
