Abstract
An IC card having a memory for receiving data from and sending data to a data reader/writer includes a reading-completion detection circuit for detecting if each sense amplifier in the IC card has completed data reading from the memory and a control circuit which ignores a command sent from the data reader/writer when no reading completion detection signal is output from the data reading-completion detection circuit upon verifying a password sent from the data reader/writer.
