The event was a huge success and attracted several hundreds of attendees.<\/p>\n<p>In a well-received speech during the EDA\/IP Session, Shine Chung, Chairman of Attopsemi, presented the topic \u201cI-fuse\u2122: A Disruptive OTP Technology \u201d In the OTP(One-Time Programmable) IP technologies, we defied the conventional wisdom of breaking a fuse to maintain a permanent programmed state forever, Attopsemi\u2019s I-fuse\u2122 is actually a \u201cnon-breaking\u201d fuse. \u201cI don\u2019t mind to break a fuse, but I do care about breaking a fuse by explosion\u201d, said Shine Chung, Chairman of Attopsemi. \u201cThe I-V curve of programming a fuse beyond the break point actually shows more like an explosion. The anti-fuse OTP also ruptures gate oxide by explosion. On the contrary, I-fuse\u2122 is a disruptive OTP technology without disrupting a fuse.\u201d<\/p>\n<p>Comparing with the other OTP technologies on 22nm and beyond, I-fuse\u2122 can be programmed at 1.0V, while the other anti-fuses need 4-5V to program. I-fuse\u2122 can be programmed at 1.0mA, while the eFuse needs up to 100mA to program. \u201cWe had small IP size because we don\u2019t need charge pumps as in anti-fuse or floating-gate OTP. We had low program voltage than the anti-fuse because ours is current programming. We had low program current because we program our I-fuse\u2122 below a catastrophe breaking point, which is different from conventional eFuse OTP.\u201d stated by Shine Chung.<\/p>\n<p>An I-fuse\u2122 OTP that can be read with merely 0.4V and 1uA was also mentioned in this symposium with details. \u201cWe defied the conventional wisdom of using a MOS as an amplifier that requires to be biased in high voltage and high current to sense the resistance. Instead, we used time-based sensing techniques that never used in memory design before,\u201d said Shine Chung, \u201cBy using MOS as switches to enable discharging two capacitors, through cell and reference cell respectively, and compare the discharge rates, the resistance in the cell can be determined higher or lower than the reference resistance so as to convert into logic data. The read energy consumed is only 1\/100 of the conventional sensing, which is good for energy harvest IoT application. Eventually most IoT devices will be battery-less.\u201d<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/static.designandreuse.com\/news_img19\/20191120_1.jpg\" alt=\"\" width=\"480\" height=\"360\" longdesc=\"https:\/\/static.designandreuse.com\/news_img19\/20191120_1.jpg\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hsinchu, Taiwan, &#8211; Nov 20, 2019 Attopsemi Technol [&hellip;]<\/p>\n","protected":false},"author":19,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[104,109],"tags":[],"class_list":["post-8828","post","type-post","status-publish","format-standard","hentry","category-104","category-2019-zh-hant"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.9 -
