Abstract

PURPOSE:To obtain a memory featuring the reduced amount of power consumption and suited for the miniature apparatus by providing the P- and N-type MOS transistors in correspondence to logic data 1 or 0 and with no use of complicated control signals in the reading exclusive memories arranged into the lattice formation. CONSTITUTION:P- and N-type MOSFET16 and 17 are connected in correspondence to logic data 1 and 0 between output signals lines (13, 14, 15) and address selection lines (10, 11, 12) of the reading exclusive memories arranged into the lattice formation. When logic data 1 is given to address selection line 10, logic data 0 is given to the rest lines 11 and 12. Thus, the gate potential is decided by line 10, and FET16, 17 and 18 are made to conduct to deliver output data 100 to output signal lines 13, 14 and 15 each. In such constitution, the reading can be carried out without using complicated control signals, thus realizing reduction of the power consumption.
