Abstract

An RFID tag LSI (100) is equipped with a recall control circuit (111) for executing a recall operation in which polarization information stored in the ferroelectric capacitors of a 6T4C-type FeRAM (110) is output to volatile storage nodes, the 6T4C-type FeRAM (110) comprising six transistors and four ferroelectric capacitors. The recall control circuit (111) executes the recall operation in the interval after the RFID tag LSI (100) generates power in response to a radio signal transmitted from a reading/writing device (120) and before the radio signal including a predetermined command is received.
