Abstract:
1. A storage media control circuit for controlling inputs and outputs to and from a plurality of types of storage media of different shapes and specifications, comprising: detection terminals for detecting a state of connection of respective ones of the storage media of the plurality of types; input/output terminals for inputting and outputting bi-directional input/output data to and from a storage medium whose connection has been detected by said detection terminals; buffers connected to the input/output terminals and holding at least one of output data and bi-directional input/output data, wherein the number of output signal buffers for holding output data and the number of input/output signal buffers for holding bi-directional input/output data is controllably settable; interface controllers for controlling interface to respective ones of the storage media of the plurality of types; and control means between the interface controllers and the buffers, for selecting one interface controller from among the interface controllers and connecting the selected interface controller to the buffers, and for setting the number of output signal buffers and the number of input/output signal buffers, wherein the selecting and the setting are based on signals from the detection terminals.
