Information processing apparatus and storage medium control method

摘要

An FDD interface (30) and a semiconductor memory control interface (32) share a signal line (38), and are connected to a control circuit. The control circuit includes a status register for storing which one of the FDD interface (30) and the semiconductor memory control interface (32) holds a privilege of using the shared signal line (38). This circuit electrically disconnect a connection between the shared signal line (38) and any one of the interfaces (30, 32) according to a state stored in the status register. In this way, a configuration of an information processing apparatus using the semiconductor memory control interface (32) and the FDD interface (30) is simplified, and can be provided inexpensively. <IMAGE>
