Abstract: PURPOSE: A solid state drive device and a driving method thereof are provided to reduce average response time by managing a memory controller not to exceed deadline time. CONSTITUTION: An input/output interface part stores an input/output command transmitted from a host(130). A memory controller(120) processes the input/output command. A first and a second input/output context sequentially process the input/output command that is transmitted from the input/output interface part. An input/output scheduler controls the operation of the first and the second input/output context. The input/output scheduler stops the operation of the first input/output context when the execution time of the input/output command exceeds deadline time and transmits the next input/output command to the second input/output context.
