Abstract
Disclosed are examples of apparatuses including memory devices and systems comprising memories sharing a common enable signal, wherein the memories may be put into different power modes. Example methods for setting the different power modes of the memories are disclosed. In some examples, different power modes may be set by issuing memory group-level commands, memory-level commands, or combinations thereof.
Claims20
An apparatus, comprising:
- a memory group including a plurality of memories configured to receive an active enable signal at a memory group and in response to the active enable signal, transition the plurality of memories from a first mode of operation to a second mode of operation, wherein the memory group is further configured to receive a select command to select a selected memory of the plurality of memories for a memory operation, wherein the memory group is further configured to receive a group-level command and, in response to the group-level command, transition unselected memories of the memory of the plurality of memories to a third mode of operation.
An apparatus, comprising:
- a memory group including a plurality of memories configured to receive an active enable signal at a memory group and, in response to the active enable signal, transition the plurality of memories from a first mode of operation to a second mode of operation, the memory group further configured to receive separate commands for each of the plurality of memories of the memory group except a selected memory from the plurality of memories of the memory group and in response to the separate commands for each of the plurality of memories except the selected memory individually transition each of the plurality of memories except the selected memory into a respective second power mode, wherein each of the separate commands includes an address associated with a respective memory of the plurality of memories and a setting for the respective memory of the plurality of memories.
An apparatus, comprising:
- a memory group including a plurality of memories configured to transition from a first power mode a second power mode in response to an enable signal, wherein the plurality of memories is further configured to receive a group-level feature command, wherein the group-level feature command includes a set of sub-feature parameters, the set of sub-feature parameters including a respective sub-feature setting for each memory of the of memories, wherein, in response to the group-level feature command, a selected memory of the plurality of memories is configured to receive a respective sub-feature setting to set the selected memory of the plurality of memories of the memory group to a selected status wherein each unselected memory of the plurality of memories is configured to transition into a respective desired power mode based on the respective sub-feature setting of the sub-feature parameters, wherein the respective desired power mode is selected from a group comprising a first power mode, a second power mode, and a third power mode, and wherein the first power mode, the second power mode, and the third power mode are different from each other.
