Abstract

PURPOSE: To make lower the effect of parasitic capacitance of sense line, by determining the sense line of a conductive type transistor forming memory elements in connection with a given current supply means and potential detection means to a smaller range than the power supply voltage.
CONSTITUTION: When a column line 23 is grounded and memory conductive type transistor M6, the gate of which is connected to a row line 24, is selected, transistors 27, 30 of a current supply means 25 are ON, and the potential of the sense line S6 is a voltage VS6 in the range smaller than the power supply voltage VDD determined with resistors R1, R2. The value of this voltage VS6 is a value based on equations I, II by taking the margin voltage as 0.2V according to the memory content 0,1 of the transistor M6, and it is detected via a transistor 33 of a potential detection means 26. Accordingly, the difference of the potential VS6 of the sense line S6 when the memory content is 1,0, is a small valtage like 1V, the effect of parasitic potential C6 on the sense line S6 is small and the operating speed can be increased. VTN is a threshold value of the transistor 33 and ΔV is an overvoltage.
