Abstract
There are provided methods and devices for providing overdrive voltages to address lines to help prevent leakage current in semiconductor memories, such as configuration memories used with programmable logic devices. Specifically, for example, there is provided a memory that includes an array of memory cells. Each memory cell includes a retainer circuit. An access transistor is coupled to the retainer circuit. An overdrive voltage level may be applied to the access transistor.
