Abstract
A word line driving circuit and a semiconductor device using the same are disclosed. The word line driving circuit includes a second pad separated from a first pad, the first pad being applied with a first ground voltage, the second pad being applied with a second ground voltage, and a word line driver supplied with the second ground voltage, the word line driver driving word lines.
Claims18
A word line driving circuit comprising:
- a row decoder supplied with a first ground voltage from a first pad, for decoding an address to generate a decoded signal;
- a first driver supplied with a second ground voltage from a second pad and configured to receive the decoded signal and generate a first word line signal for activation of a main word line and a word line select signal for selection of a sub-word line to be activated;
- an inverter for inverting the word line select signal;
- and
- a second driver supplied with the second ground voltage from the second pad and configured to receive the output signal of the inverter and the first word line signal and generate a second word line signal for activation of the sub-word line.
