Claim Text:
1. A memory, comprising: a first bit line, a second bit line, and a memory cell, a first isolation cell and a second isolation cell which are disposed in a same column, wherein the first isolation cell, the second isolation cell and the memory cell have a same structure, wherein the first isolation cell comprises: a substrate, a first control gate structure, a second control gate structure, a first floating gate structure, a second floating gate structure and a word line structure that are disposed on the substrate, and a first doped region and a second doped region disposed in the substrate, wherein the first floating gate structure is disposed on the substrate between the first doped region and the word line structure, the second floating gate structure is disposed on the substrate between the second doped region and the word line structure, the first control gate structure is disposed over the first floating gate structure, and the second control gate structure is disposed over the second floating gate structure, wherein a first doped region of the memory cell is connected with the first bit line, a second doped region of the memory cell is connected with the second bit line, the second doped region of the first isolation cell is connected with the first bit line, and a first doped region of the second isolation cell is connected with the second bit line, and wherein the first doped region of the first isolation cell serves as a connection terminal of the first isolation cell, the first control gate structure and the second control gate structure of the first isolation cell are connected together to serve as a control terminal of the first isolation cell, a second doped region of the second isolation cell serves as a connection terminal of the second isolation cell, and a first control gate structure and a second control gate structure of the second isolation cell are connected together to serve as a control terminal of the second isolation cell.
