摘要： In an IC (integrated circuit) card, a CPU (central processing unit) is connected to a data bus and an address bus. A data memory is connected to the data bus and the address bus. The data memory is a rewritable memory, such as EEPROM (electrically erasable programmable read only memory) or battery backed-up RAM (random access memory). The data memory is segmented into a predetermined number of sectors each consisting of predetermined bytes. An external processing device, such as a terminal device is connected to the data bus and the address bus, via a one-bit I/O line and a port. The terminal device supplies a processing instruction via the I/O line to the third port. The CPU receives the processing instruction via the data bus, analyzes the instruction, and reads out and executes the necessary program. The CPU supplies the results of each processing to the terminal device, by way of the data bus, the port and the I/O bus.

摘要： An integrated circuit card having a one-chip micro computer, a memory, and an address bus and data bus for coupling the micro computer and the memory, includes an input/output bus and interface for communication with an external terminal device. The micro computer executes processing commands from the external device, and returns the processing results to the external device through the interface. Instead of returning the processing results to the micro computer immediately when processing is finished, the IC card includes a timer for measuring elapsed time starting with the receipt of a processing command. The processing results are returned to the external device only when a predetermined elapsed time has been measured by the timer. Therefore, the return of the processing results, (for example, the determination as to whether a PIN is correct) is not dependent upon the processing time, making it impossible for a user of the external device to determine the type of processing command and the results of the processing based on the processing time.
