Adaptive Memory Refresh Control

A memory device comprising:

• at least one memory array;
• and
• control circuitry configured to:
• access host-device refresh-timing information, the host-device refresh-timing information received in association with a first command from a host device;
• and
• determine a self-refresh schedule for a memory cell of the at least one memory array based at least in part on the host-device refresh-timing information.

A host device comprising:

• an interface;
• and
• control circuitry coupled to the interface, the control circuitry configured to:
• receive memory-device refresh-timing information from a memory device in response to the host device issuing a first command to the memory device;
• and
• determine a refresh-command schedule for the memory device based at least in part on the memory-device refresh-timing information.

A method, comprising:

• receiving host-device refresh-timing information at a memory device from a host device, the host-device refresh-timing information associated with a first command received at the memory device;
• determining a self-refresh schedule at the memory device based at least in part on the host-device refresh-timing information;
• determining memory-device refresh-timing information;
• and
• transmitting the memory-device refresh-timing information to the host device in response to receiving a second command at the memory device from the host device.

A method, comprising:

• receiving memory-device refresh-timing information at a host device from a memory device, the memory-device refresh-timing information received in response to transmitting a first command to the memory device;
• determining a refresh-command schedule at the host device based at least in part on the memory-device refresh-timing information;
• determining host-device refresh-timing information based at least in part on the refresh-command schedule;
• and
• transmitting the host-device refresh-timing information to the memory device in association with a second command.
