Abstract
A data storage device includes a storage unit; and a controller configured to select a write mode by analyzing a tendency of commands received from a host device, and operate in the selected write mode to write data to the storage or to read data from the storage.
Claims21
A data storage device comprising:
- a storage;
- and
- a controller configured to select a write mode by analyzing a tendency of commands received from a host device, and operate in the selected write mode to write data to the storage or to read data from the storage.
A data storage device comprising:
- a storage;
- a controller configured to control data exchange with the storage in response to commands received from a host device;
- a command analyzer configured to analyze the commands;
- a workload analyzer configured to analyze a tendency of the commands based on the analysis result of the command analyzer;
- and
- a write mode decision component configured to select a write mode which supports a program suspend function or a write mode which does not support the program suspend function based on the analysis result of the workload analyzer.

A method of operating a data storage device which includes a storage and a controller for controlling data exchange with the storage, the method comprising the steps of:
- analyzing a tendency of commands received from a host device;
- and
- selecting a write mode based on a result of the analyzing operation.
A storage system comprising:
- a host device;
- and
- a data storage device comprising a storage and a controller configured to write data to the storage or read data from the storage,
- wherein the controller selects a write mode by analyzing a tendency of commands received from the host device, and operates in the selected write mode to write data to the storage.
1 more element
A storage device comprising:
- a storage;
- and
- a controller suitable for controlling the storage to perform a write operation and a read operation,
- wherein the controller is suitable for:
- receiving commands from a host device;
- determining a tendency of write and read commands included in the received commands in a set period;
- generating a program command, selected from a normal program command and a cache program command, based on the determined tendency;
- and
- providing the storage with the selected program command,
- wherein the storage is suitable for:
- in response to the cache program command, caching data corresponding to a current program command while writing data corresponding to a previous program command;
- and
- in response to the normal program command, after completing writing data corresponding to the previous program command, writing data corresponding to the current program command.
