Abstract: A voltage for reference at a voltage level higher than a target value is produced from a constant current provided from a constant current generating circuit, and is subjected to resistance division by a resistance division circuit to produce a reference voltage at the target level, and then a final reference voltage is produced by a voltage follower. An internal voltage generating circuit thus provided can generate the reference voltage having the desired voltage level with high accuracy as well as an internal voltage based on the reference voltage by controlling temperature characteristic even with a low power supply voltage.

Abstract: A voltage adjusting circuit includes a transistor connected in a current mirror, and a resistor element connected to the transistor. The resistor element has a resistance that changes with temperature, so the voltage level is adjusted according to variations in temperature. Accordingly, stable control of an internal circuit in which desirable operating characteristics change with temperature can be attained, even when temperature varies.

Abstract: A connection gate circuit includes first and second N channel MOS transistors connected in series between a first bit line of a pair of bit lines and a first global IO line of a pair of IO lines, and third and fourth N channel MOS transistors connected in series between a second bit line of the pair of bit lines and a second global IO line of the pair of IO lines. The first and second N channel MOS transistors have their gates receiving a sense amplifier activation signal activating a sense amplifier. The third and fourth N channel MOS transistors have their gates receiving a column selection signal.

Abstract: In a voltage adjusting circuit, a transistor forming a current mirror, and a resistor element connected to the transistor are provided. By forming the resistor element with a resistor material having resistor characteristics that changes based on temperature variation, the voltage level can be adjusted corresponding to variations in the temperature. Accordingly, stable control of the internal circuit in which desirable operating characteristics changes corresponding to variations in temperature can be attained, even when temperature vanes.
