Abstract:
An electrical fuse (eFuse) bit cell includes a program transistor, a read transistor, and an eFuse. The program transistor has a first program terminal, a second program terminal, and a third program terminal. The read transistor has a first read terminal, a second read terminal, and a third read terminal. The eFuse has a first end and a second end. The first end, the first program terminal, and the second read terminal are coupled together. The read transistor is configured to be off and the program transistor is configured to be on when the eFuse bit cell is in a program mode. The program transistor is configured to be off and the read transistor is configured to be on when the eFuse bit cell is in a read mode.
