A communication device comprising:

• a network control circuit controlling transmission and reception of a data item for a network;
• a first storage circuit connected to said network control circuit, and temporarily storing the received data item;
• a second storage circuit connected to said first storage circuit, and storing data item;
• and
• a control circuit controlling said data items stored in said first storage circuit and said second storage circuit to be transferred to a predetermined buffer, wherein
• said control circuit includes:
• a first transfer control circuit controlling said first storage circuit to transfer said data item stored in said first storage circuit to said buffer in response to a request to store data in said buffer, when the request is issued before preset time passes since said data item has been stored in said first storage circuit;
• and
• a second transfer control circuit controlling said second storage circuit to transfer said data item stored in said first storage circuit to said second storage circuit when the preset time passes since said data item has been stored in said first storage circuit, and to transfer said data item stored in said second storage circuit to said buffer in response to the request to store data in said buffer.
