Adaptive word-line boost driver |
摘要 |
A word line driver circuit includes a first transistor having its gate coupled to a first node configured to receive a word line select signal. A second transistor has its gate coupled to the first node and a drain coupled to a drain of the first transistor at a second node that is coupled to a word line. A word line assist control circuit is coupled to the first node, to the word line, and to a gate of a third transistor. The word line assist control circuit is configured to turn on or turn off the third transistor to adjust a voltage of the word line. |
