Original Abstract Submitted
According to one embodiment, a memory card includes a nonvolatile memory and a controller. The controller performs initialization of an interface, determines a maximum performance that can be supported from among a plurality of performance predetermined for stream recording, based on a bus configuration of the interface determined at the interface initialization and a maximum allowable power consumption set during the interface initialization, and generates a data set stored in a power state register specified by an NVMe™ standard, which is a power state set in which each of all performance smaller than the determined maximum performance among the plurality of performance corresponds to a power state, to indicate a list of the performance which can be supported for a host.
