Abstract

PURPOSE:To an input voltage control circuit suitable for a sense amplifier for an ROM enabling high speed readout less in voltage dependancy with a simple constitution, by feed-back controlling a voltage at a connecting point between a memory matrix and a load transistor. CONSTITUTION:A readout voltage at a coupling point P1 between a memory matrix 1 and a load use depletion type FETQ1 is given between a sense amplifier 2 and a point P1 and inputted to an input voltage control circuit 3 of FETsQ12-Q14 constitution. When the information (0) of a cell to be selected in a matrix 1 is read, the potential at the point P1 is increased to be a sense level or more. Then, the FETQ12 turns on and the FETQ14 in ground connection via the FETQ13 turns on, the impedance of the FETQ14 is lowered to decrease the potential at the point P1 with feedback control. This is the same when the information is 1, and the voltage at the point P1 is controlled to a specified value and the deterioration in the transient characteristics at inverse information readout is not caused, allowing to achieve a suitable input controller for a sense amplifier for an ROM enabling high speed readout with less in voltage dependancy and simple constitution.
