Abstract: A storage device comprises a nonvolatile memory configured to store data that is written in size units of a mapping size, and a storage controller configured to transmit a command to the nonvolatile memory. The storage controller includes a host interface configured to receive a write command from a host device, the write command including a command to write first data to a first address, the first data having a first size smaller than the mapping size. The storage controller includes processing circuitry configured to transmit a read command to the nonvolatile memory, to cause the nonvolatile memory to read second data stored in the nonvolatile memory addressed based on the first address, in response to a determination that the first size is smaller than the mapping size and before the first data is received at the storage controller through the host interface.

Abstract: A memory device executes a method of controlling power of the memory device. The memory device includes a host interface which receives a command from a host and controls an access to the memory device by the host, a register which is accessible by the host and includes a plurality of different regions, a memory access monitor which monitors which region of the plurality of regions the host accesses, and in response thereto generates a monitoring signal, and a power control manager which selects a power-up group of modules of the memory device in accordance with the monitoring signal and which supplies power to the selected power-up group of modules while not supplying power to any modules of the memory device not belonging to the selected power-up group.

Abstract: A storage device includes a non-volatile memory; a plurality of cores; a host interface configured to receive a first set command, an I/O command, and an ADMIN command from a host; and a storage controller including a command distribution module configured to be set to a first state according to the first set command, and distribute the I/O command to the plurality of cores according to the set first state. Each of the plurality of cores may be configured to perform an operation instructed by the I/O command and an operation instructed by the ADMIN command on the non-volatile memory in response to the distributed I/O command.
