- sanxiyn 3y agoI believe this report by WikiChip from IEDM 2022 is an accurate summary of the situation: > While there were a great number of interesting papers from both academia and industry, it was the one by TSMC that brought frighteningly bad news: whereas logic is still scaling more-or-less along the historical trendline, SRAM scaling appears to have completely collapsed. https://fuse.wikichip.org/news/7343/iedm-2022-did-we-just-witness-the-death-of-sram/ https://fuse.wikichip.org/news/7343/iedm-2022-did-we-just-wi...
