Abstract
In some embodiments, the present disclosure relates to a one-time program (OTP) memory cell. The OTP memory cell includes a read transistor and a program transistor neighboring the read transistor. The read transistor includes a read dielectric layer and a read gate electrode overlying the read dielectric layer. The program transistor includes a program dielectric layer and a program gate electrode overlying the program dielectric layer. The program transistor has a smaller breakdown voltage than the read transistor.
