Abstract
An example method that includes determining a leakage characteristic of a driver having a driver output coupled to a signal line; providing a leak detection signal and a keeper control signal to a latch based on the leakage characteristic; setting a latch logic state of the latch based on the keeper control signal; and setting a standby logic state of the driver output based on the latch logic state.
Claims20
An apparatus comprising:
- a data path comprising:
- a signal line;
- a repeater circuit including:
- a receiver configured to receive data along the data path, the data having a logic state;
- and
- a driver configured to transmit the data along the data path;
- and
- a keeper circuit coupled to a node at an output of the driver and configured to set a standby logic state of the node, the keeper circuit including:
- a keeper control circuit configured to determine a leakage characteristic of the driver and provide a leak detection signal and a keeper control signal based on the leakage characteristic;
- and
- a latch coupled to the signal line, the latch configured to have a latch logic state based on the keeper control signal and further configured to set the standby logic state of the output of the driver based on the latch logic state.

An apparatus comprising:
- a tri-state data driver configured to transmit data along a data path and coupled to a signal line;
- and
- a keeper circuit coupled to a node at an output of the tri-state data driver, the keeper circuit comprises:
- a keeper control circuit configured to determine a leakage characteristic of the tri-state data driver based on leakages of transistors of the tri-state data driver;
- and
- a latch configured to set a standby logic state of the output of the tri-state driver based on the leakage characteristic.
