Information processing apparatus and semiconductor device

A semiconductor device comprising:

• a controller that controls an operation of a device;
• an interface that temporarily stores data input from the device;
• a writing unit that controls writing of data on a volatile memory;
• a first communication pathway that connects the interface to the writing unit and is used to transmit the data acquired by the interface to the volatile memory and to transfer the data written on the volatile memory;
• a second communication pathway that connects the interface to the writing unit and does not share a route with the first communication pathway;
• and
• a switching unit that switches a communication path used to transmit data from the interface to the volatile memory from the first communication pathway to the second communication pathway if the interface has received image data from the device.
