Abstract
Apparatuses and methods of operating memory are described. One such method can include receiving a select command at a plurality of memory volumes of a memory device, the select command indicating a targeted memory volume of the plurality of memory volumes. In response to the select command, the method can include selecting the targeted memory volume of the memory volumes and putting at least a portion of a non-selected memory volume of the memory volumes in a particular state based, at least in part, on a previous state of the non-selected memory volume and/or a portion of an address associated with the select command.
Claims18
A method of operating memory, comprising:
- receiving a select command at a plurality of memory volumes of a memory device;
- and
- responsive to the select command indicating a targeted memory volume of the plurality of memory volumes:
- selecting the targeted memory volume;
- and
- putting at least a portion of a non-selected memory volume of the plurality of memory volumes in a particular state based, at least in part, on a previous state of the at least portion of the non-selected memory volume;
- and
- responsive to the select command not indicating a targeted memory volume of the plurality of memory volumes, reverting each memory volume of the plurality of memory volumes to its respective state prior to an activation of each memory volume.
An apparatus, comprising:
- a plurality of memory devices comprising a plurality of memory volumes, wherein the apparatus is configured to:
- activate the plurality of memory volumes of the plurality of memory devices by switching a shared signal provided thereto from a first state to a second state;
- subsequently provide a command to the plurality of memory devices;
- wherein, responsive to the command indicating a targeted memory volume of the memory volumes, the targeted memory volume remains active and executes a subsequent command received;
- put at least a portion of an unselected memory volume of the plurality of memory volumes in a reduced power state based, at least in part, on a previous power state of the at least portion of the unselected memory volume
- wherein, responsive to the command not indicating any of the plurality of memory volumes as a targeted memory volume, the apparatus is configured to revert each memory volume of the plurality of memory volumes to its respective state prior to switching the shared signal.
A method of operating memory, comprising:
- receiving a select command and an associated select address at a plurality of memory volumes of a memory device, wherein responsive to a portion of the select address indicating a targeted memory volume of the plurality of memory volumes;
- selecting the targeted memory volume responsive to the select command and the portion of the select address;
- and
- putting at least a portion of a non-selected memory volume of the plurality of memory volumes in a particular state based, at least in part, on a previous state of the at least portion of the non-selected memory volume;
- and
- responsive to the select command not indicating a targeted memory volume of the plurality of memory volumes, reverting each memory volume of the plurality of memory volumes to a respective state prior to an activation of each memory volume.
