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.

Storage devices and methods for operating the devices

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.

Storage device and storage system including the same

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.
