Abstract:
1. A control device configured to control data transfer between a host device, a first storage configured as a nonvolatile storage for storing data, and a second storage configured as a nonvolatile random access memory having faster write speed than the first storage, the control device comprising: a data write processing unit configured to control the second storage to store data input from the host device sequentially when a write request signal requesting to write data stored in the host device to the first storage, and to control the second storage to read out predetermined size of data and control the first storage to store the read out data when the write request signal is input and size of data stored in the second storage reaches the predetermined size; and a data readout processing unit configured to control the first storage to read out stored data and to output the read out data to the host device without the second storage when a read out request signal requesting to read out data stored in the first storage to the host device.
