To date, for large system integrations, various optically reconfigurable gate arrays (ORGAs) have been developed to realize both fast reconfiguration and numerous reconfiguration contexts. Optically differential reconfigurable gate arrays (ODRGAs) present advantageous capabilities compared with ORGAs: they have increased reconfiguration frequency per unit of laser power and reduced optical power consumption. Dynamic optically reconfigurable gate arrays (DORGA) can realize the highest gate density. Nevertheless, an important disadvantage of DORGAs is that their reconfiguration frequency is lower than that of ODRGAs and their optical power consumption is greater than that of ODRGAs. Therefore, a novel inversion/non-inversion dynamic optically reconfigurable gate array incorporating only the good attributes from both architectures has been developed. This paper presents a novel inversion/non-inversion ORGA using a rewritable MEMS holographic memory. ©2009 IEEE.
