Abstract
Methods, apparatuses, and systems related to managing operations performed in response to refresh management (RFM) commands. A controller generates the RFM command for coordinating a refresh management operation targeted for implementation at an apparatus. The apparatus tracks refresh target set that includes refresh management target locations within the apparatus. According to the tracked refresh management target set, the apparatus selectively implements the targeted refresh management operation and/or a response operation in addition to or as a replacement for the targeted refresh management operation.
Claims20
A method, comprising:
- receiving, at a memory device from a memory controller external to the memory device, a refresh management (RFM) command for refreshing the memory device;
- and
- determining, at the memory device in response to receiving the RFM command, whether to perform a refresh operation on an address of the memory device during a time associated with the RFM command.
A method, comprising:
- receiving, at a memory device from a memory controller external to the memory device, a refresh management (RFM) command for refreshing the memory device;
- and
- performing, at the memory device during a time associated with the RFM command, one or more operations selected by the memory device in response to receiving the RFM command.
An apparatus, comprising:
- a memory array of a memory device;
- an input circuit of the memory device configured to receive command signals and address signals;
- and
- a refresh control circuit of the memory device configured to determine, in response to the memory device receiving a refresh management (RFM) command via the input circuit, whether to perform a refresh operation on an address of the memory array during a time associated with the RFM command.
