Abstract
The present disclosure includes apparatuses and methods for performing operations by a memory device in a self-refresh state. An example includes an array of memory cells and a controller coupled to the array of memory cells. The controller is configured to direct performance of compute operations on data stored in the array when the array is in a self-refresh state.
Claims20
A memory device, comprising:
- an array of memory cells;
- and
- control circuitry coupled to the array and configured to:
- enter a self-refresh state;
- and
- while in the self-refresh state, operate in a selected one of a plurality of modes, wherein the plurality of modes includes:
- a first mode in which the memory device is configured to perform operations in addition to refresh operations on the array;
- and
- a second mode in which the memory device is configured to not perform operations in addition to refresh operations on the array.
6 more elements
An apparatus, comprising:
- an array of memory cells;
- and
- control circuitry coupled to the array and configured to:
- receive commands from a host when the host is operating in a first power mode;
- operate in a self-refresh state in association with the host entering a second power mode;
- and
- while operating in the self-refresh state, operate in a selected one of a plurality of modes, wherein the plurality of modes includes:
- a first mode in which the control circuitry is configured to perform background operations in addition to self-refresh operations;
- and
- a second mode in which the control circuitry is configured to perform self-refresh operations without performing background operations in addition to self-refresh operations.
7 more elements
A processing in memory device, comprising:
- a mode register configured to provide a number of selectable operation modes associated with a self-refresh state of the processing in memory device, wherein the number of selectable modes comprises:
- a first mode in which the processing in memory device is configured to perform processing in memory operations in addition to self-refresh operations;
- and
- a second mode in which the processing in memory device is prevented from performing processing in memory operations in addition to the self-refresh operations;
- and
- control circuitry configured to, while in the self-refresh state, operate the processing in memory device in accordance with the selectable operation mode indicated by the mode register.
