发明名称 Wordline driver
摘要 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.

主权项 1. A circuit comprising: a signal generation circuit; a first transistor of a first type having a drain, a source, and a gate; a second transistor of the first type having a drain, a source, and a gate; and a first transistor of a second type having a drain, a source, and a gate, wherein the circuit is configured to have the drain of the first transistor of the first type coupled to the source of the second transistor of the first type;a first voltage value at the source of the first transistor of the first type;a first control signal at the gate of the first transistor of the first type;the drain of the second transistor of the first type serve as a wordlinea third voltage value at the source of the first transistor of the second type;a second control signal at the gate of the first transistor of the second type;the first transistor of the first type and the second transistor of the first type provide the first voltage value for the wordline;the first transistor of the second type provide the third voltage value for the wordline;a same second voltage value at the gate of the second transistor of the first type when the wordline has the first voltage value and when the wordline has the third voltage value; andthe signal generation circuit generate the first control signal and the second control signal, the first control signal having a first logically high level when the second control signal has a second logically high level, the first control signal having a first logically low level when the second control signal has a second logically low level, the first logically high level being different from the second logically high level, and the first logically low level being different from the second logically low level.
