Abstract
For identification purposes, a network is added to a multiply configurable microminiature array. During fabrication of the array, the connection pattern of the network is established to be uniquely representative of the particular circuit then being formed in the array. In response to interrogation signals applied to the array, the network provides a unique pattern of voltages representative of the particular circuit. During actual operation of the array, the identification network is in effect automatically disconnected therefrom.
