ABSTRACT:
A word-line driver has an input from a word-line decoder and an output to drive a word-line. The word-line driver comprises a plurality of inverters connected in series between the input and output including a first and a second inverter with a first node designating an output of the first inverter and an input of the second inverter, the first inverter having a NMOS transistor with a controllable first source, and a first pull-up circuitry coupled between a positive supply voltage and the first node and selectively activated by a first control signal, wherein when the first source is set to the positive supply voltage and the first control signal is set to a complementary supply voltage of the positive supply voltage, the first node is pulled up to the positive supply voltage to ensure an output of the second inverter is pulled down to the complementary supply voltage.
