One-time programmable capacitive fuse bit and a memory

A memory, comprising a one-time programmable capacitive fuse bit, wherein the one-time programmable capacitive fuse bit comprises an upper plate (3), the upper plate comprises a plurality of fuses (5) arranged side by side and spaced by an internal from each other, middle portions of adjacent fuses are connected to each other;

• a connecting portion connected to the fuse is disposed above two ends and the middle portion of each of the plurality of fuses;
• the fuse bit further comprises a lower plate (2) corresponding to the two ends and the middle portion of the fuse, the lower plate is disposed below the fuse;
• the lower plate corresponding to the middle portion of the fuse is opposite to the connecting portion corresponding to the middle portion of the fuse;
• a hollow portion (4) is disposed between the lower plate corresponding to the middle portion of the fuse and the lower polar plate corresponding to both ends of the fuse, and a projection of an edge of both ends of the fuse is located in the hollow portion.
