Abstract
A memory including non-volatile memory. The memory system also includes a controller that controls data transfer between a host and the non-volatile memory, and a power supply unit that supplies a voltage to the controller. Further, the controller includes a power supply control unit that determines the voltage supplied to a module in the controller on the basis of an operation condition determined with the host. The power supply unit adjusts the voltage supplied to the module in accordance with a command from the power supply control unit.
Claims15
A memory system comprising:
- a non-volatile memory that stores user data received from a host;
- a controller that controls data transfer between the host and the non-volatile memory;
- and
- a power supply that supplies a voltage to the controller,
- wherein the controller includes:
- a power supply control unit that determines the voltage supplied to a module in the controller on the basis of an operation condition determined with the host, the operation condition being a PCIe interface speed that is determined with the host, and
- a PCIe controller that performs data communication with the host using a communication interface based on PCIe specification,
- wherein the power supply unit adjusts the voltage supplied to the module in accordance with a command from the power supply control unit.
A memory system comprising:
- a non-volatile memory that stores user data received from a host;
- and
- a controller that controls data transfer between the host and the non-volatile memory,
- wherein the controller includes:
- a clock management unit that supplies an operation clock to a module in the controller, and
- a PCIe controller for performing data communication with the host using a communication interface based on PCIe specification,
- wherein the clock management unit adjusts a clock frequency supplied to the module in the controller on the basis of an operation condition determined with the host, the operation condition being a PCIe interface speed that is determined with the host.
A controller comprising:
- a memory interface that performs data transfer with a non-volatile memory storing user data from a host;
- a host interface that performs data transfer with the host;
- a power supply control unit that determines a voltage supplied to a module in the controller on the basis of an operation condition determined with the host and commands a power supply to supply the determined voltage;
- and
- a clock management unit that adjusts a clock frequency sent to the module in the controller on the basis of the operation condition determined with the host.
