Abstract
A memory device based on thyristors, comprises the following elements. A plurality of gate structures, are continuous structures in the first direction. A plurality of bit lines, extending in a second direction substantially perpendicular to the first direction. A plurality of source lines, extending in the first direction. A plurality of channels, extending in a third direction substantially perpendicular to the first direction and the second direction, and penetrating the gate structures. The first doped regions of the channels are coupled to the bit lines, and the second doped regions of the channels are coupled to the source lines. A plurality of memory units formed by the gate structures and corresponding channels. The source lines are arranged in sequence according to the second direction to form a stair structure, and the lengths of the source lines decrease in sequence in the first direction.
