Refresh rate control for a memory device

Last updated:

Abstract:

Methods, systems, and devices for refresh rate control for a memory device are described. For example, a memory array of a memory device may be refreshed according to a first set of refresh parameters, such as a refresh rate. The memory device may detect an event at the memory device associated with a reduction in data integrity. In some cases, the event may be associated with a temperature of the memory device, a voltage level detected at the memory device, an error event at the memory device, or the like. As a result of detecting the event, the memory device may adapt one or more of the set of refresh parameters, such as increasing the refresh rate for the memory array. In some cases, the memory device may adapt the set of refresh parameters by increasing a quantity of rows of the memory array that are refreshed during a refresh operation, decreasing a periodicity between refresh operations, or both.
