Abstract
A gate-controlled thyristor (GCT) and CAM memory are provided. The GCT includes first, second and third transistors, each having a control end, first and second ends. The control ends of the first and second transistors are connected to a search line. The control end of the second transistor is applied with a fixed bias voltage, and the second end of the second transistor is connected to the first end of the first transistor. The second end of the third transistor is connected to the first end of the second transistor, and the first end is connected to a match line. Based on the search line voltage, a search bit is determined to compare the data and the search bit to determine whether the search bit matches the data. This configuration may be applied to 3D NAND memory, having a high capacity and performance.
