Abstract
High-speed data transfer is performed in a storage device having a plurality of semiconductor memories while an increase in power consumption is prevented. In a memory controller, a request transfer unit transfers a request for demanding transfer of data and data based on the request to each of a plurality of memories in synchronization with a clock signal. A busy time measurement unit measures a busy time which is a time required for access based on the request, for a selected memory which is one memory out of the plurality of memories. A clock signal adjustment unit substantially equalizes the measured busy time of the selected memory and a total time required for transferring the requests and the data for the plurality of memories except the selected memory by adjusting a frequency of the clock signal.
