ABSTRACT:
A word line supply circuit reducing the capacitance operating as a load at a time of enabling a word line in a semiconductor memory, resulting in the internal voltage supply being more stable. A word line voltage supply circuit is provided for directly driving the word line by the internal voltage supply Vpp and whereby pulling up the word line to the Vpp level. A row decoder 100 receives a voltage from a Vcc power supply and receives an address signal and outputs an RDout signal that selects a predetermined number of a word line group. A reset level converter 200 receives a voltage from a Vpp power supply which is a higher voltage level than Vcc, and receives the RDout signal and a RESET signal for resetting the word line and outputs a RESET signal. A word line driver controller 300 receives a voltage from the Vpp power supply and receives the RDout signal, RESET signal and a pre-decoder signal as inputs and outputs a WLEN signal, which is a word line control signal. A word line driver 400 receives a voltage from the Vpp power supply and applies the Vpp voltage to one word line by the WLEN signal.
