Abstract
The present disclosure discloses an electronic device, a memory system, and a power control method, which belong to the field of storage technology. A disclosed electronic device can comprise a host and a memory system. The host can comprise a power management unit, and a first interface configured to send an identifier indicating a peak power capability supported by the power management unit. The memory system can comprise at least one memory device coupled with the host, a second interface communicated with the first interface and configured to receive the identifier, and a memory controller coupled to the memory device and configured to determine a peak power management policy matches the peak power capability according to the identifier.
Claims20
A memory system, including:
- a memory device;
- and
- a memory controller comprising an interface communicated with a host, coupled with the memory device, and configured to:
- receive, through the interface, an identifier indicating a maximum power capability supported by the host;
- replace a first maximum power management policy preset in the memory controller with a second maximum power management policy according to the maximum power capability;
- and
- control, by adjusting a clock frequency of the memory system, an operating power of the memory system less than or equal to the maximum power capability.
An electronic device, including:
- a host, comprising:
- a power management unit, and
- a first interface configured to send an identifier indicating a maximum power capability supported by the power management unit;
- and
- a memory system, comprising:
- a memory device, and
- a memory controller comprising a second interface communicated with a first interface of the host, and configured to:
- receive, through the second interface, an identifier indicating a maximum power capability supported by the host;
- replace a first maximum power management policy preset in the memory controller with a second maximum power management policy according to the maximum power capability;
- and
- control, by adjusting a clock frequency of the memory system, an operating power of the memory system less than or equal to the maximum power capability.
A power controlling method, comprising:
- sending, through a first interface of a host, an identifier indicating a maximum power capability supported by the host;
- receiving, by a second interface in a memory controller of a memory system communicated with the first interface, the identifier;
- replacing, by the memory controller, a first maximum power management policy preset in the memory controller with a second maximum power management policy according to the maximum power capability;
- and
- controlling, by the memory controller, by adjusting a clock frequency of the memory system, an operating power of the memory system less than or equal to the maximum power capability.
