Matchline sense circuit and method |
June 3, 2008 |
| A matchline sense circuit for detecting a rising voltage on a matchline of a CAM array is disclosed. The circuit initially precharges a matchline to ground before turning on a current source to supply current to the matchline and raise the voltage of the matchline. A reference matchline |

Duty-cycle regulator |
May 20, 2003 |
| A duty-cycle regulation method for deriving an output clock signal having a predetermined duty cycle from an input clock signal having an arbitrary duty cycle. Once the input clock signal is received, an output clock storage element is switched to a first state upon detecting a transitio |
