Abstract

See full text

Embodiments are provided that include a circuit for generating voltage in a memory. One such circuit includes a charge pump circuit including a first transistor, a high-voltage switch circuit, and a cut-off switch circuit arranged to reduce leakage current from the charge pump circuit. The cut-off switch circuit includes a second transistor, wherein an output of the charge pump circuit is coupled to one of a source node and a drain node of the second transistor, and a first control signal is input at a gate of the second transistor. Further embodiments provide a method for generating voltage. One such method includes enabling a first transistor coupled to an output of a charge pump circuit when the charge pump is operating and disabling the first transistor coupled to the output of the charge pump circuit when the charge pump circuit is not operating.
