Abstract

A circuit includes a first transistor and a second transistor of a first type. The circuit further includes a first transistor of a second type. A first first-type drain is coupled to a second first-type source. A first first-type source is configured to have a first voltage value. A first first-type gate is configured to have a first control signal. A second first-type drain is configured to serve as a wordline. A second first-type gate is configured to have a second voltage value. A first second-type source is configured to have a third voltage value. A first second-type gate is configured to have a second control signal. The first transistor and the second transistor of the first type are configured to provide the first voltage value for the wordline. The first transistor of the second-type is configured to provide the third voltage value the wordline.
