US 12,578,781 B2 · Bank configurable power modes

Abstract

Methods, systems, and devices for bank-configurable power modes are described. Aspects include operating a memory device that has multiple memory banks in a first mode. While operating in the first mode, the memory device may receive a command to enter a second mode having a lower power consumption level than the first mode. The memory device may enter the second mode by switching a first subset of the memory banks to a first low power mode that operates at a first power consumption level and a second subset of the memory banks to a second low power mode that operates at a second power consumption level that may be lower than the first power consumption level. In some cases, the memory device may switch the first subset of memory banks from the first low power mode while maintaining the second subset of memory banks in the low power mode.

Dependent claims

A method, comprising:

operating a plurality of memory banks in respective first modes, wherein the plurality of memory banks are within one or more memory devices;
receiving, via a command bus and at the one or more memory devices while operating the plurality of memory banks in the respective first modes, a single command that comprises a bitmap that indicates to operate a first memory bank of the plurality in a second mode corresponding to a lower power consumption level than a respective first mode for the first memory bank, wherein each bit of the bitmap indicates a respective mode of one or more memory banks of the plurality of memory banks;
and
switching, based at least in part on receiving the bitmap, the first memory bank from the respective first mode for the first memory bank to the second mode while maintaining a second memory bank of the plurality in a respective first mode for the second memory bank.

1 more element

A memory system, comprising:

one or more memory devices;
and
processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
operate a plurality of memory banks in respective first modes, wherein the plurality of memory banks are within the one or more memory devices;
receive, via a command bus and at the memory system while operating the plurality of memory banks in the respective first modes, a single command that comprises a bitmap that indicates to operate a first memory bank of the plurality in a second mode corresponding to a lower power consumption level than a respective first mode for the first memory bank, wherein each bit of the bitmap indicates a respective mode of one or more memory banks of the plurality of memory banks;
and
switch, based at least in part on receiving the bitmap, the first memory bank from the respective first mode for the first memory bank to the second mode while maintaining a second memory bank of the plurality in a respective first mode for the second memory bank.
