Abstract
A memory circuit includes a voltage boosting circuit for generating a voltage that exceeds a voltage supply of the voltage boosting circuit. The voltage boosting circuit includes a first transistor having a first polarity type and a second transistor having a second polarity type opposite the first transistor. The first transistor is a planar transistor, a source of the first transistor being connected with the voltage supply, and a gate of the first transistor receiving a control signal. The second transistor includes a gate formed in at least two planes. A source of the second transistor is connected with the voltage supply, a gate of the second transistor receives the control signal, and a drain of the second transistor is connected with a drain of the first transistor and forms an output of the voltage boosting circuit for generating a boosted supply voltage as a function of the control signal.
