A storage controller for writing first data to a first memory cell by performing programming of the first memory cell N-times, where N is a positive integer greater than 1, includes a write amplification manager and a central processing unit. The write amplification manager checks whether the first data is invalid data before an Nprogramming of the first memory cell is performed, and the central processing unit does not perform the N-th programming of the first memory cell when the first data is the invalid data.

Storage controller and storage device including the same

A host receives information related to garbage collection of a storage device, and the host controls selective execution of garbage collection by the storage device according to the received information.

Host-driven garbage collection

A method is for adaptively adjusting a user storage region in an entire storage region of a nonvolatile memory system. The method includes a host transmitting a user region information request command to the nonvolatile memory system, the nonvolatile memory system transmitting user region information to the host, the host changing the user region information, the host transmitting a user region information setting command to the nonvolatile memory system, and the nonvolatile memory system controlling a size of the user storage region in response to the user region information setting command.

A method of controlling a storage device comprises monitoring whether a quality of service (QoS) of the storage device satisfies a quality condition set through a host, and adjusting a current setting of at least one operation metric of the storage device related to the QoS, according to a result of the monitoring.

Monitoring and control of storage device based on host-specified quality condition

A host receives information related to garbage collection of a storage device, and it controls selective execution of garbage collection by the storage device according to the received information.
