Instead of relying on unstable physical parameters such as device resistance, which are prone to environmental interference, the new design encodes analog computing weights through highly stable device geometry ratios, fundamentally overcoming a key limitation in analog computation precision.<\/p>\n<p>The Nanjing University team designed and validated an analog in-memory computing chip fabricated using standard CMOS processes. By integrating weight remapping technology, the chip achieved a record-setting root-mean-square error (RMSE) of just 0.101% in parallel vector\u2013matrix multiplication \u2014 marking the highest precision ever reported for analog vector\u2013matrix computations.<\/p>\n<p>Remarkably, the chip demonstrated stable performance under extreme temperature conditions, operating reliably from \u201378.5 \u00b0C to 180 \u00b0C, with RMSE values maintaining at 0.155% and 0.130%, respectively. The team also conducted tests in strong magnetic fields, finding that the core unit\u2019s output current varied by no more than 0.21% compared with results under zero-field conditions \u2014 underscoring the robustness and environmental resilience of the design.<\/p>\n<p>(Photo credit: FREEPIK)<\/p>\n<p><a href=\"https:\/\/www.trendforce.com\/landingPage\/selected_topics_semiconductor\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-3786 size-full\" src=\"https:\/\/www.newsbeep.com\/nz\/wp-content\/uploads\/2025\/10\/AIServer-728_90.png\"   alt=\"\" width=\"728\" height=\"90\"\/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Analog computing \u2014 a computing paradigm distinct from traditional digital approaches \u2014 leverages the inherent laws of physics&hellip;\n","protected":false},"author":2,"featured_media":83479,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[21],"tags":[371,111,139,69,145],"class_list":{"0":"post-83478","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-computing","8":"tag-computing","9":"tag-new-zealand","10":"tag-newzealand","11":"tag-nz","12":"tag-technology"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/83478","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=83478"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/83478\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/83479"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=83478"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=83478"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=83478"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
