Abstract
The present disclosure includes apparatuses and methods related to refresh in memory. An example apparatus can refresh a memory cell of an array of memory cells in response to the array of memory cells being accessed a threshold number of accesses.
Claims34
An apparatus, comprising:
- an array of memory cells;
- a counter configured to:
- determine an access count of the array of memory cells;
- and
- a controller configured to:
- refresh a memory cell of the array of memory cells in response to the access count of the array of memory cells being a threshold number.

An apparatus, comprising:
- an array of memory cells;
- a counter configured to:
- determine an access count of the array of memory cells;
- and
- a controller configured to:
- determine a refresh rate of the array of memory cells;
- and
- refresh a memory cell of the array of memory cells in response to the access count of the array of memory cells being a threshold number, wherein the threshold number is based on the refresh rate.

An apparatus, comprising:
- an array of memory cells;
- a counter configured to:
- determine an access count of the array of memory cells;
- and
- a controller configured to:
- determine a refresh rate of the array of memory cells;
- and
- refresh a memory cell of the array of memory cells that was last accessed in response to the access count of the array of memory cells being a threshold number, wherein the threshold number is based on the refresh rate and the refresh rate is based on a miss rate of the array of memory cells.
