Abstract: According to one embodiment, a host interface circuit includes a physical layer that performs communication with a host, and a protocol control circuit that determines a transfer rate between the physical layer and the host. When a temperature detected by a temperature sensor becomes equal to or higher than a first temperature, the protocol control circuit changes the transfer rate from a first transfer rate to a second transfer rate. The protocol control circuit transitions to a first mode in which a change of the transfer rate based on a first request from the host is prohibited.

Abstract: A memory system includes a nonvolatile memory that stores table data and a memory controller for writing and reading data to and from the nonvolatile memory. The memory controller includes a volatile memory that can be in either a retention state during which power is supplied thereto or a power down state during which the power supplied thereto is cut off, a timer that measures elapsed time starting from when the memory system transitions to the low power state, and a register in which previously measured elapsed times are stored, and in which a current measured elapsed time is stored when the memory system wakes up from the low power state. The controller controls the transitioning of the volatile memory from the retention state to the power down state, if the measured elapsed time is greater than a threshold value, which is calculated based on the previously measured elapsed times.
