Abstract
A laser programmable integrated circuit chip has a plurality of logic modules organized as rows and columns. The modules and other chip components are connected by a grid-like array of conductors. The conductors are initially unattached. Customization occurs by fusing laser diffuseable links and severing cut points on the conductors. The modules have continuous conductor lines running through them. These conductor lines aid in testing and are useful in routing and error avoidance. The chip also contains test registers to test the array of logic modules, the input/output blocks, and the conductors.
