Abstract
A wordline driver includes a pre-driver, a sub-wordline driver and a transmission circuit. The pre-driver generates a wordline enable signal and a wordline disable signal based on one or more selection signals, a decoded address signal, and one or more timing control signals. The transmission circuit transmits the wordline enable signal and the wordline disable signal. The sub-wordline driver controls a voltage level of the sub-wordline based on the wordline enable signal and the wordline disable signal that are transmitted by the transmission circuit. Therefore, driving capacity may be improved.
Claims20
A wordline driver comprising:
- a pre-driver configured to generate a wordline enable signal and a wordline disable signal based on one or more selection signals, a decoded address signal and one or more timing control signals;
- a transmission circuit configured to transmit the wordline enable signal and the wordline disable signal;
- and
- a sub-wordline driver configured to control a voltage level of a sub-wordline based on the wordline enable signal and the wordline disable signal that are transmitted by the transmission circuit.
A memory device comprising:
- a plurality of sub-cell arrays coupled to a plurality of sub-wordlines and partitioned into a plurality of areas;
- a pre-driver configured to generate a wordline enable signal and a wordline disable signal for driving the plurality of sub-wordlines based on one or more selection signals, a decoded address signal, and one or more timing control signals;
- a transmission circuit configured to transmit the wordline enable signal and the wordline disable signal;
- and
- a sub-wordline driver configured to control voltage levels of the plurality of sub-wordlines based on the wordline enable signal and the wordline disable signal.
A method of driving a wordline in a memory device, the method comprising:
- generating a wordline enable signal and a wordline disable signal based on one or more selection signals, a decoded address signal, and one or more timing control signals;
- transmitting the wordline enable signal and the wordline disable signal;
- and
- controlling a voltage level of a sub-wordline based on the transmitted wordline enable signal and the transmitted wordline disable signal.
