Abstract:
A memory cell includes a first select transistor, a first following gate transistor, an antifuse transistor, a second following gate transistor, and a second select transistor. The first select transistor has a first terminal coupled to a bit line, a second terminal, and a gate terminal coupled to a word line. The first following gate transistor has a first terminal coupled to the second terminal of the first select transistor, a second terminal, and a gate terminal coupled to a following control line. The antifuse transistor has a first terminal coupled to the second terminal of the first following gate, and a gate terminal coupled to an antifuse control line. The second following gate transistor and the second select transistor are disposed symmetrically to the first following gate transistor and the second select transistor with respect to the antifuse transistor.
