Paper Abstract

The commercialization of CD ROM drives has clearly demonstrated the ability of optical storage devices to meet the growing demand for archival data storage. However, with the continued expansion of electronic information resources, storage capacity requirements are expected to approach the terabit level for personal users and exceed the petabit level for databases and data warehouse systems. Further, many data intensive applications will also require real time access data access rates. Thus, designers for the next generation of archival storage systems have the challenging task of providing storage capacities several orders of magnitude larger than existing systems while maintaining current data access times. To meet this challenge, we have been developing a 'smart' read-head device for large capacity, page-oriented optical storage systems. Further the device is designed to operate as a data filter that will pass only valid data between the optical storage system and the host computer. Based on a photonic VLSI device technology, our data filter monolithically integrates optical detectors, photoreceivers circuits, data manipulation logic, and filter control circuitry onto a single CMOS chip that can be readily fabricated using a standard VLSI fabrication facility. Thus, our device is compatible with existing electronic device manufacturing technology and shares all of the reliability, uniformity, and manufacturability benefits associated with current, electronic hardware. This paper will present an evaluation of our latest smart pixel circuits and detail our performance expectations for a 32 X 32 bit data filter chip currently under development.
