<p>PURPOSE:To reduce power consumption and to improve write characteristic without reducing the capacity of a memory, by forming a switching means to a signal line by a series circuit of an FET. CONSTITUTION:A writing circuit 80 contains a controlling circuit 11 for generating a true complementary output of an address, based on an address Ai, and a switching means. The switching means is formed by connecting in series an E-P FET. For instance, the switch means which is connected to a word line W1 is formed by connecting alternately in series an E-P FET (Q1.1, Q3.1,...Q2n-1.1) to which true outputs of the address are inputted, and a D-P FET (Q2.1, Q4.1,...Q2n.1) to which complementary outputs -A1--An of the address are inputted. By such a switching means, this circuit is controlled so that only means is turned on in accordance with the address, and other all means are turned off.</p> |
