Abstract
A method and wordline voltage boosting circuit for implementing boosted wordline voltage in memories, and a design structure on which the subject circuit resides are provided. The wordline voltage boosting circuit receives a precharge signal, uses a switching transistor coupled to a bootstrap capacitor, and generates a boosted voltage level responsive to the precharge signal. The boosted voltage level is applied to a voltage supply of an output stage of a wordline driver, causing the wordline voltage level of a selected wordline to be boosted. The switching transistor is controlled by the precharge signal and a node of the bootstrap capacitor supplying the boosted voltage level is driven high by the switching transistor.
