Abstract
An antifuse programming circuit for performing a programming operation without causing any stress to an antifuse element is provided. The antifuse programming circuit includes: an antifuse element which is programmable according to a voltage difference between both terminals thereof; a control logic circuit for generating a control signal in response to internal address signals and an external address signal; a negative voltage generator, coupled to the antifuse element, for generating a negative voltage signal; and a power connection controller, in response to the control signal, for coupling the negative voltage signal to a ground terminal when the antifuse element is in an unprogrammed state.
Claims6
An antifuse programming circuit, comprising:
- an antifuse element being programmable according to a voltage difference between both terminals thereof;
- a control logic means for generating a control signal in response to internal address signals and an external address signal;
- a negative voltage generation means, coupled the antifuse element, for generating a negative voltage signal;
- and
- a power connection control means, in response to the control signal, for coupling the negative voltage signal to a ground terminal when the antifuse element is in an unprogrammed state.
