METHOD USING ELECTRICALLY RECONSTITUTABLE GATE ARRAY LOGIC AND DEVICE CONSTITUTED BY THE SAME

PROBLEM TO BE SOLVED: To temporarily convert software into a constitution of hardware which temporarily and actually operates by installing an interface structure and providing an electrical path transferring signal information between an outer system and a designated function logic element in a device, which has the function logic element and which can electrically be reconstituted. SOLUTION: L chips of one set has at least two logic chips and a memory module and a user designation device module in addition. A mutual connection chip which can be constituted is connected to all the L chips, which can mutually be connected with I/O pins. A host interface is connected to a host computer, a constituting system, and all devices which can be used for the input/ output or control of data. The constitution system is connected to the host interface, all the L chips which can be constituted and the mutual connection chip. The realizer hardware operates under the control of the host computer.
