Abstract

A field programmable array logic circuit is described wherein existing sensing circuitry is employed along with circuitry to enable every fuse location to be isolated, so that both a.c. and verification testing takes place under the same conditions, i.e. voltage levels and frequency, which occurs during normal operation of the programmed circuit.
