An OTP (One-Time Programmable) or MTP (Multi-Time Programmable) memory module with a dual-cell structure comprises a memory array, a data selector, a sense amplifier and a controller; two adjacent memory cells form one group in the memory array during operation in a dual-cell mode, and the two memory cells are referred to as a first cell and a second cell respectively, and the first cell and the second cell constitute a differential dual-cell structure; when the first cell is "1" and the second cell is "0", the output passing through the sense amplifier is "1", and when the first cell is "0" and the second cell is "1", the output passing through the sense amplifier is "0", that is, the final output of the dual-cell structure is one bit. The reliability of the OTP or MTP memory module is improved during operation in a differential dual-cell mode, and meanwhile, applications under different situations are combined together to flexibly meet the demands and also achieve the highest cost performance. |
