Method and circuit for driving word line of memory cell
First Claim
1. A method of driving a word line connected to memory cells, comprising:
- enabling the word line to a boosting voltage level during a first period of a word line enable period; and
enabling the word line to an internal power voltage level during a second period of the word line enable period.

Abstract
A method and circuit are provided for driving a word line. The word line driving circuit includes first and second power drivers, a switching unit and a word line driver. The first power driver is driven to a boosting voltage level and the second power driver is driven to an internal power voltage level. The switching unit transfers a first output of the first power driver to the word line driver in response to a first switching signal and transfers a second output of the second power driver to the word line driver in response to a second switching signal. The word line driver alternately drives a word line to the first output and the second output transferred from the switching unit in response to a word line driving signal.
