Definition: antifuse
A programmable chip technology that creates permanent, conductive paths between transistors. In contrast to "blowing fuses" in the fusible link method, which opens a circuit by breaking apart a conductive path, the antifuse method closes the circuit by "growing" a conductive via. Two metal layers sandwich a layer of non-conductive, amorphous silicon. When voltage is applied to this middle layer, the amorphous silicon is turned into polysilicon, which is conductive.

The antifuse technology creates closed circuits by turning non-conductive silicon into a conductive pathway (see via).
