The fuse array described herein is very compact and uses little semiconductor area because of its crosspoint architecture. The disclosed crosspoint architecture reduces the number of conductors that must be run horizontally or vertically through each bit cell. As a result, the area required for each bit cell is significantly reduced. In one embodiment, a selected set of voltages on various wordlines and bitlines are used to program the fuses to produce programmed fuses having a tighter distribution of impedances. Similarly, a selected set of voltages on various wordlines and bitlines are used to read the fuses.
