METHOD AND APPARATUS FOR INCREASING YEILD IN AN ELECTRONIC CIRCUIT

摘要

An electronic circuit includes multiple circuit elements arranged into multiple distinct subdivisions, each subdivision having a separate voltage supply connection for conveying power to the subdivision. The electronic circuit further includes a controller including multiple outputs, each of the outputs being connected to a corresponding one of the voltage supply connections. When a given one of the subdivisions does not include a weak circuit element, the controller supplies a first voltage level to the given subdivision via the corresponding voltage supply connection. When the given subdivision includes at least one weak circuit element, the controller is operative to supply at least a second voltage level to the given subdivision via the corresponding voltage supply connection, the second voltage level being greater than the first voltage level.
