This study introduces the first programmable optically reconfigurable gate array (ORGA) architecture, eliminating the need for disassembly to reprogram holographic memory. This innovation enables easier reprogramming of high-capacity VLSI systems.

Area of Science:

Integrated circuits
Optical computing
Holographic data storage

Background:

Optically reconfigurable gate arrays (ORGAs) offer massive virtual gate counts exceeding current VLSIs.
Holographic memory enables teragate-scale VLSI production.
Conventional ORGAs lack post-fabrication reprogrammability, requiring complex disassembly and reassembly.

Purpose of the Study:

To propose and validate the world's first ORGA architecture enabling in-situ reprogramming.
To overcome the reprogramming limitations of existing ORGA designs.
To enhance the practicality and reusability of ORGA technology.

Main Methods:

Development of a novel ORGA architecture facilitating non-disassembly reprogramming.
Experimental validation of the proposed architecture's functionality.
