A non-volatile memory cell includes an ion well of a semiconductor substrate; a first half-transistor having a firs select gate, a first diffusion region in the ion well, and a first gate dielectric layer between the first select gate and the ion well; a second half-transistor disposed adjacent to the first half-transistor, wherein the second half-transistor has a second select gate spaced apart from the first select gate, a second diffusion region in the ion well, and a second gate dielectric layer between the second select gate and the ion well. The first and second half-transistors are mirror-symmetrical to each other.
