    摘要： A semiconductor integrated circuit is disclosed, in which a group of sense amplifiers activated at the same time by a selection signal on a selection signal line are divided into a plurality of blocks, and a power-source line for driving sense amplifiers is formed for each sense amplifier block so as to cross the selection signal line. Alternatively, an input/output line is divided into a plurality of sub-input/output lines, and a plurality of input/output lines are formed so that each input/output line crosses its sub-input/output lines, to form a hierarchical structure with respect to input/output lines. Thus, the load capacitance of each power-source line is reduced, and the time constant of each of the charging and discharging of the load capacitance is decreased. That is, the above semiconductor integrated circuit can operate at high speed.

    摘要： The present invention is intended to operate a semiconductor device at high speed with low voltage. A circuit configuration is used in which 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 is provided which 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 is provided which converts a data line supply voltage or word line supply voltage to a higher voltage. Therefore, stabilized signal transmission is ensured.
