Abstract
Methods for operating a memory device can include monitoring communications from a host device for a notification that a battery of the host device has entered a charging state and performing a background operation of the memory device responsive to receiving this notification. The notification can be an added functionality incorporated into a standardized interface.
Claims20
A memory device comprising:
- an interface coupled to receive communications from a host device;
- and
- a memory controller, comprising:
- pulse pattern detection circuitry coupled to the interface and configured to monitor the communications and to detect a notification that a battery of the host device has entered a charging state;
- and
- a processor configured to initiate a background operation of the memory device responsive to receiving the notification.
3 more elements
A method of operating a system, comprising:
- at a host comprising a battery:
- determining whether the battery is being charged;
- and
- in response to determining that the battery is being charged, providing a first signal at one or more selected pins of a physical interface providing communication with a storage system;
- and
- at the storage system:
- receiving the first signal at the one or more selected pins of the physical interface;
- determining whether the first signal meets a first configuration indicating that the host is being charged;
- and
- in response to determining that the first signal meets the first configuration, enabling the storage system to perform a background operation.
7 more elements
A system, comprising:
- a host, comprising:
- a processor;
- a battery;
- a charge detection and signaling circuit, including,
- a sensor configured to detect externally-supplied charging power to the battery, and
- a signaling circuit coupled to receive a sensor signal from the sensor and to generate a first signal at one or more selected pins of a physical interface coupled to a storage system;
- and
- a storage system, comprising:
- an array of memory cells;
- and
- a memory controller including one or more processors, the memory controller configured to perform operations comprising,
- receiving the first signal from the one or more selected pins of the physical interface;
- determining whether the first signal meets a first configuration indicating that the host is being charged;
- and
- in response to determining that the first signal meets the first configuration, causing the storage system to perform a memory management operation.
