Abstract: A method for reading data of a nonvolatile storage device is provided to synchronize data transmission by operating a storage FSM(Finite State Machine) and a host FSM in parallel without firmware change, by using a register capable of being accessed by the storage FSM and the host FSM at the same time as a time stamp register. According to a method for reading data of a nonvolatile storage device(330), data of a first number of blocks are read from the nonvolatile storage device and then data of the blocks are stored in a data buffer(360). In correspondence to storage the block data in the data buffer, first time stamp is increased and is stored in a time stamp register(370). It is determined to transmit the data of the blocks stored in the data buffer to a host(310), by comparing the first time stamp with second time stamp.
