There is provided an operation method of a memory system which includes a host and a storage device, and the operation method includes allocating a portion of a host memory included in the host for a host memory buffer to be used by a controller of the storage device, setting a set feature command such that the host memory buffer is enabled, setting a retention command including information about a response speed of the host memory buffer, selecting an operation mode of the host memory buffer, based on the retention command, and selecting one of a plurality of power states, which the controller supports, based on a performance objective of the operation mode of the host memory buffer.

Memory system using host memory buffer and operation method thereof

A storage device includes a controller and a nonvolatile memory device having memory cells and reference memory cells. The controller accesses first memory cells of the memory cells, reads first reference memory cells, which are associated with the first memory cells, from among the reference memory cells when the access to the first memory cells fails, determines a bad area depending on a read result of the first reference memory cells, and identifies second memory cells, which belong to the bad area, from among the memory cells to bad memory cells.

Storage device including nonvolatile memory device, nonvolatile memory device, operating method of storage device

The method of operating the data storage device includes performing channel distribution non-sequentially based on a logical address included in a data signal and outputting a channel address, and at least one of writing data to and reading stored data from a memory connected to one of a plurality of channels based on the channel address.

Method of operating data storage device and device thereof

A data storage device includes a flash memory including a plurality of data blocks and a flash translation layer that divides the plurality of data blocks into a data block of a first group and a data block of a second group, and that records the data signal to a data block of the first group or a data block of the second group which is extended from a data block of the first group.
