Abstract

A communication device including a receiving unit, a command processing unit, an updating unit, a transmitting unit, and a selector is provided. The receiving unit receives a transmitted command. The command processing unit performs command processing in response to the received command and generates a response containing a result of the command processing. The updating unit updates information held in one area of a memory currently disabled using the result of the command processing, wherein a first area and a second area form the memory for holding information indicating a current status. The transmitting unit transmits the generated response. The selector switches the one area currently disabled and holds the information that was updated using the result of the command processing into the enabled state and the other area currently enabled into the disabled state immediately after transmission of the response is completed.
