Patent attributes
A memory controller and a decoder are provided. The decoder is adapted to the memory controller. The decoder includes a first transistor to a fourth transistor. Gates of the first to the fourth transistor are coupled to a first to a fourth control signal respectively. A first terminal and a second terminal of the first transistor are coupled to a first voltage and a first terminal of the second transistor respectively. First terminals and second terminals of the third transistor and the fourth transistor are coupled to a second terminal of the second transistor and a second voltage respectively. When the first transistor and the second transistor are turned off, a voltage of the second control signal is lower than a voltage of the first control signal. Thereby, a gate-induced drain leakage (GIDL) current of the transistors is reduced.
