Abstract
A controller for a storage device is connected to a host system and the storage device. A buffer memory includes first and second storage areas. A timer counts a preset given time in response to an instruction to start counting and sends a deadline notification when A given time is elapsed. A command responding portion, when receiving a read command from the host system, instructs the timer to start counting and thereafter outputs a read instruction to read data from the storage system. A data processing portion, in response to the read instruction by the command responding portion, reads specified data from the storage device and holds the read data in the second storage area of the buffer memory. A read control portion sends the host system the data held in the second storage area of the buffer memory when the deadline notification is received from the timer.
