Abstract
A non-volatile memory cell circuit is used to replace a polysilicon fuse as an enabling element for a redundant row or column of memory cells in a semiconductor memory array. The fuse is divided into read and program sections, allowing a large device to be used for reading and a small device to be used for programming, thus permitting programming of all fuses in a redundant row simultaneously with minimal current consumption. The circuit may be embodied as a five-device or a four-device configuration.
