    • A memory cell array includes a plurality of memory cells arranged in a matrix form. A word line and a power supply line respectively are connected in common to the plurality of memory cells arranged in each row. A power supply line/word line control circuit is connected to each word line and each power supply line. In accessing the plurality of memory cells row by row, the control circuit raises the voltage of the power supply line and, after the voltage of the power supply line reaches the high voltage at all the positions, starts activation of the word line. On the other hand, in turning from the access state to the non-access state, the control circuit deactivates the word line and, after the voltage of the word line changes to the ground voltage at all the positions, changes the voltage of the power supply line to the low voltage.

    • A voltage control circuit is connected to a voltage source. The voltage control circuit changes voltages of n different values and outputs them to an output node of the voltage control circuit according to control signals. A first switch element is connected between the output node of the voltage control circuit and a reference voltage node, and a second switch element is connected between the output node of the voltage control circuit and an output node of the voltage source. The first switch element is controlled so as to be conductive when the voltage control circuit changes the voltage of the output node from a first voltage to a second voltage that is lower than the first voltage, and the second switch element is controlled so as to be conductive when the voltage control circuit changes the voltage of the output node from a second voltage to a first voltage.

    • An ECL output buffer circuit is constituted by an output buffer circuit main portion and its control circuit. In the output buffer circuit main portion, an output from a differential switch is input to the base of a bipolar transistor (emitter follower). The emitter of the bipolar transistor is connected to an output terminal. A ground potential is applied to the collector of the bipolar transistor. One end of the channel conductive path of a MOS transistor is connected to the base of the bipolar transistor. The other end of the channel conductive path is connected to a power-supply terminal via a constant-current source. The control circuit controls the ON/OFF operation of the MOS transistor and the output level of the bipolar transistor. When the output buffer circuit main portion is to be set in a standby state, the control circuit performs control to set the MOS transistor in an ON state and set the output of the bipolar transistor at low level.
