PROBLEM TO BE SOLVED: To enable reduction in electrical power consumption by providing the detection circuit with a sense amplifier connected to a memory array, with a data storage device connected between the sense amplifier and the output data bus, and with a data feedback circuit having an input terminal connected to the output data bus and an output terminal connected to the data storage device. SOLUTION: The data detected by the sense amplifier 21 are outputted from the sense amplifier 21 and supplied to the input of the data storage device 13. The digital sense amplifier, possessing no DC power element, requires no DC power from a memory cell. The data storage device 13 receives the data, latching or storing them for the purpose of transmitting to the output data bus 17. The data storage device 13 is equipped with a data register, latch and other mechanism suitable for storing data. The data output from the sense amplifier 21 and the input in the data storage device 13 are overwritable by the dynamic latch and new incoming data.
