SMART CARD, DETECTOR AND SEMICONDUCTOR INTEGRATED CIRCUIT HAVING SHARE BLOCK AND UNIQUE BLOCK

摘要

A smart card, a detector and a semiconductor integrated circuit having a share block and a unique block are provided to share elements commonly used by a plurality of detectors to reduce the number of detectors and decrease the area of an integrated circuit including the detectors. A smart card(200) includes a common detector(210), a detection control unit(230) and a reset control unit(240). The common detector includes a plurality of detectors each of which has a share block(224) and a unique block. The plurality of detectors commonly use the share block and respectively have unique blocks(221,222,223). The detection control unit controls the common detector such that the plural detectors perform detecting operations in different time periods. The reset control unit controls a reset operation of the smart card in response to a signal detected by the common detector.
