    摘要： An improved voltage level detecting circuit that provides stable voltage detection. The voltage level detecting circuit senses a level of a voltage to be detected only when two clock signals are at a low level after ORing the signals. After detecting the voltage level, the circuit reduces power consumption by preventing a current path between the voltage and ground. Consistent operation of the voltage level detecting circuit is achieved despite fluctuation of the voltage level to be detected caused by noise through detecting the level of the voltage only when a specific clock signal is enabled.

    摘要： An improved word line driving circuit for a memory device reduces a driving speed difference between an assistant word line driving unit, which is closest to a memory cell block selection unit, and an assistant word line driving unit, which is farthest from the memory cell block selection unit, for selecting a block of memory cell. Further, the improved circuit substantially allows a non-overlap margin between word lines by differing the size of an assistant word line driving unit connected to each word line according to its location. The improved circuit also includes a memory cell block selection unit for outputting a block selection signal so as to select a memory cell block, a plurality of main word line driving units for outputting a main word line signal, and a plurality of assistant word line driving units.
