Abstract
An eFuse cell is provided. The eFuse cell may include a first PMOS transistor and a first NMOS transistor configured to receive a programmed state selection (BLOWB) signal, a second PMOS transistor and a second NMOS transistor configured to receive a write word line bar (WWLB) for a program operation, a first read NMOS transistor and a second read NMOS transistor configured to receive a read word line (RWL) for a read operation, a program transistor configured to control a program current to flow for a fusing operation, and an eFuse connected between the first read NMOS transistor and the second read NMOS transistor.
