Re-Programmable Antifuse FPGA Utilizing Resistive CeRAM Elements

摘要

A novel architecture utilizing resistive Correlated Electron Random Access Memory (CeRAM) elements to build re-programmable antifuse Field Programmable Gate Array (FPGA) components is introduced. Unlike traditional antifuse switching elements that can become permanently conducting upon application of the programming voltage, CeRAM antifuse elements can be subsequently switched back to an insulating state upon application of a reset voltage allowing the designer the freedom to re-configure the FPGA. Because the CeRAM element is based on a metal-insulator-metal (MIM) stack structure, it can be easily integrated in the upper metal layers of the fabrication process virtually eliminating the need for routing of channels between logic blocks. By utilizing CeRAM structures in the routing resources and as the block memory, it is possible to enhance the density by as much as 6 times, significantly reducing the size of the array while maintaining the use of existing low power logic styles.View full textDownload full textKeywordsAntifuse, CeRAM, FPGA, Resistive MemoryRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10584587.2011.573729
