The present invention relates to the use of a programmable soft fuse for disabling a signal line using an electronic switching circuit, a latch, a control circuit, and a reset circuit. In another preferred embodiment, a precharge device is included.A method of disabling a data line using a soft fuse is disclosed, where the steps are: providing a soft fuse having a control means, providing a memory array, providing an address decoder, connecting the soft fuse between the address decoder and the memory array, testing the memory array, locating a bad address line in the array, entering the location of the bad address line into the address decoder, and strobing the control means.A further method is disclosed, which has the additional steps of: providing shifting circuitry, connecting the shifting circuitry to the address decoder, the soft fuse circuitry, and the memory array accepting data from the address decoder into the shifting circuitry, and providing the data to at least one predetermined row in the memory array.
