A semiconductor device disclosed herein is provided with a plurality of function reconfigurable cells, each comprising a memory circuit and a control circuit, for realizing variable logical functions. A function reconfigurable cell autonomously controls a read address in the memory circuit storing true value data by itself. For example, the control circuit takes feedback input of information that has been read from the data field and control field of the memory circuit synchronously and uses feedback input information from the data field or another information as address information for next synchronous reading of the data field and control field, based on feedback input information from the control field. Because each function reconfigurable cell is capable of autonomous control of reading of the memory circuit storing true value data by itself, it is possible to handle the memory circuit for realizing variable logical functions as a circuit equivalent to a logic circuit. It is thus possible to provide flexibility of logical configurations and scalability that can be realized. Further, it becomes possible to realize variable logical functions that can accommodate a large logical element in a limited chip area occupied for memory.
