  • Patent number: 11972136
    Abstract: A method of operating a memory system, which includes a memory controller and at least one non-volatile memory, includes storing, in the memory system, temperature-dependent performance level information received from a host disposed external to the memory system, setting an operation performance level of the memory system to a first performance level, operating the memory controller and the at least one non-volatile memory device according to the first performance level, detecting an internal temperature of the memory system, and changing the operation performance level of the memory system to a second performance level that is different from the first performance level. The operation performance level is changed by the memory controller of the memory system, and changing the operation performance level is based on the temperature-dependent performance level information and the detected internal temperature.

  • Publication number: 20230029118
    Abstract: A current measurement apparatus for a three-phase inverter, according to one embodiment of the present invention, comprises: a current detection element connected to a lower end of one of three lower switches constituting the inverter; a current measurement unit measuring currents by using the current detection element and the two lower switches that are not connected to the current detection element; and a current correction unit for correcting, on the basis of the relationship between a first current value measured by means of the current detection element and second and third current values measured by means of the two lower switches, the second and third current values.
