PROBLEM TO BE SOLVED: To make it possible to actuate a memory provided with a built-in logic at high speed without increasing the number of the manufacturing processes of the memory, by a method wherein a first circuit comprises a type I insulated-gate field-effect transistor as its constituent element, and a second circuit comprises a type II insulated-gate field-effect transistor as its constituent element. SOLUTION: Bit line equalizing circuits 11l and 11r as a first circuit are respectively provided to a pair of bit lines BLL and ZBLL and a pair of bit lines BLR and ZBLR, and MOS transistors NT1 to NT6 are constituted of a DRAM transistor on those circuits 11l and 11r. Moreover, bit line separation gates 12l and 12r are connected with a sense amplifying circuit 13, and MOS transistors NT7 to NT10 of the gates 12l and 12r as a second circuit of the circuit 13 are constituted of a DRAM transistor. As a result, a memory provided with a built-in logic can be actuated at high speed without increasing the number of manufacturing processes of the memory.
