SEMICONDUCTOR DEVICE OPERATING WITH LOW SUPPLY VOLTAGE

摘要

PURPOSE: A semiconductor device operated at a low supply voltage is provided to operate stably a driving transistor for word line as a word driver though a supply voltage is reduced. CONSTITUTION: In the circuit, the transfer impedance between a common I/O line and a data line is changed depending on whether information is to be read or written. A current/voltage converter includes a MISFET different in conduction type to a select MISFET. Thus, the speed of reading information is increased. An intermediate voltage generator having high driving capability is provided. Thus, the circuit has sufficient driving capability for an LSI having large load capacitance. A voltage converter converts a data line supply voltage or word line supply voltage to a higher voltage. Therefore, stabilized signal transmission is ensured.
