Abstract: PURPOSE: A power management method of a storage device including a multi core is provided to reduce power consumption without the delay of a response speed of a system by independently or dependently managing power according to a command pattern received from a host. CONSTITUTION: A pattern of a command received from the outside is analyzed(S110). An operation mode of a storage device is selected based on the pattern(S120). If the operation mode is a first mode, a first processing core manages power of the storage device(S140). If the operation mode is a second mode, the first and a second processing cores separately manage power of a controlled function block(S150).

Abstract: PURPOSE: A data control method and a system using the same are provided to not transceive data between a host and a storage device for a data control command, thereby reducing communication time with the host and reducing power consumption of a storage medium. CONSTITUTION: A host transmits a data control command which makes data corresponding to the first logical block address to correspond to the second logical block address. An FTL(Flash Translation Layer) maps the second logical block address on a physical block address mapped on the first logical block address in response to the data control command.
