Abstract
The disclosure provides a data refreshing method of a memory, a controller of a memory, and a memory. The method includes that a target refreshing row in a data row of the memory is determined according to a running state of the controller, the target refreshing row including at least one data row; and in response to determining that a first refreshing interval expires and the target refreshing row includes a first reserved row, the first reserved row in the target refreshing row is refreshed. The first reserved row is a data row with data storage duration smaller than preset duration in the memory. The first refreshing interval is a refreshing interval of the first reserved row.
Claims20
A data refreshing method of a memory, applied to a controller which is configured to control the memory to perform data refreshing and data access, and comprising:
- determining a target refreshing row in a data row of the memory according to a running state of the controller;
- wherein the target refreshing row comprises at least one data row;
- and
- refreshing a first reserved row in the target refreshing row in response to determining that a first refreshing interval expires and the target refreshing row comprises the first reserved row;
- wherein the first reserved row is a data row with data storage duration smaller than preset duration in the memory, and the first refreshing interval is a refreshing interval of the first reserved row.
A controller of a memory, configured to control the memory to perform data refreshing and data access, and comprising:
- a processor;
- and
- a memory configured to store instructions executable by the processor;
- wherein the processor is configured to:
- determine a target refreshing row in a data row of the memory according to a running state of the controller;
- wherein the target refreshing row comprises at least one data row;
- and
- refresh a first reserved row in the target refreshing row in response to determining that a first refreshing interval expires and the target refreshing row comprises the first reserved row;
- wherein the first reserved row is a data row with data storage duration smaller than preset duration in the memory, and the first refreshing interval is a refreshing interval of the first reserved row.
A memory, comprising a controller and a plurality of storage units, the storage unit comprising a plurality of data rows, the storage unit being configured to store data, and the controller being configured to execute a data refreshing method of a memory, comprising:
- determining a target refreshing row in a data row of the memory according to a running state of the controller;
- wherein the target refreshing row comprises at least one data row;
- and
- refreshing a first reserved row in the target refreshing row in response to determining that a first refreshing interval expires and the target refreshing row comprises the first reserved row;
- wherein the first reserved row is a data row with data storage duration smaller than preset duration in the memory, and the first refreshing interval is a refreshing interval of the first reserved row.
