Schnell said JEDEC is targeting the second half of the 2023 to finalize the 1.0 spec, with CAMM-based systems out by next year.<\/p>\n<p>Who are the companies that voted for it? Schnell can\u2019t say, as that\u2019s up to each member to reveal, but group covers the range of suppliers, from SoC, to connectors, to OEMs, and all unanimously voted to adopt the CAMM Common Spec, with no dissenters. There are currently 332 companies listed in JEDEC, from Apple to ZTE, each involved in different aspects of memory in different industries.<\/p>\n<p>For those who haven\u2019t followed it, Dell introduced its CAMM design in April 2022 with the aim of replacing the decades old SO-DIMM design that has been used in most gaming and workstation laptops up to now. CAMM\u2019s main appeal is that it enables higher memory density while also scaling to ever higher clock speeds.<\/p>\n<p>Some of the motivation for expediency likely comes from the fast-approaching \u201cbrick wall\u201d facing laptops when SO-DIMMs hit at DDR5\/6400.<\/p>\n<p>Schnell said the CAMM spec is far from finalized, but the first JEDEC CAMM modules should take over right where SO-DIMM ends at 6400.<\/p>\n<div>\n<figure><img decoding=\"async\" loading=\"lazy\" src=\"https:\/\/b2c-contenthub.com\/wp-content\/uploads\/2022\/04\/CAMM_Patent.jpg?quality=50&#038;strip=all&#038;w=1200\" alt=\"Dell patent for a CAMM cDIMM versus a typical SO-DIMM.\" width=\"1200\" height=\"598\"><figcaption>\n<p>An illustration from Dell  shows the convoluted path the memory traces take to get from the CPU in a SO-DIMM (upper left) versus the company\u2019s new CAMM and cDIMM (lower right.)<\/p>\n<\/figcaption><\/figure>\n<p>Dell<\/p>\n<\/div>\n<h2 id=\"camm-is-not-proprietary\">CAMM is not proprietary<\/h2>\n<p>When Dell first introduced CAMM, it was somewhat misunderstood as a proprietary spec that would \u201clock customers\u201d into a design. Dell has said that\u2019s never been its intention and the fast approval seems to vindicate that.\u00a0Schnell addressed that initial concern, with the adoption underway.<\/p>\n<p>\u201cDell is a huge company, we don\u2019t keep the lights on because we get royalties for a patent,\u201d he said. \u201cWe basically want to recover the cost of inventing it, and implementing it.\u201d<\/p>\n<p>Besides, going it alone is simply not how the PC world works.<\/p>\n<p>\u201cWe\u2019re part of the PC industry and the PC industry is built out of an ecosystem of partners, suppliers all feeding in,\u201d Schnell said. \u201cYes, Dell does great innovation of our own in our systems, but we also integrate a lot of innovations from a lot of people.\u201d<\/p>\n<p>With CAMM being hammered out now, Schnell did lay out some possible paths for CAMM as it replaces SO-DIMM. DDR6 is an obvious road, he said, but CAMM even enables the possibility of LPDDR6 on a replaceable module. LPDDR, or low-power DDR RAM, has long been preferred for smaller and thinner laptops as well as phones for power savings. It\u2019s also long been implemented only as <em>soldered-on<\/em>.<\/p>\n<p>Schnell foresees a version of CAMM enabling the performance and power benefits of LPDDR, but in a replaceable and upgradeable module. With JEDEC adopting CAMM now, that future gets closer.<\/p>\n<figure>\n<p>\n<iframe loading=\"lazy\" title=\"Hands-On With Dell's Controversial CAMM Memory\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/vbnCEy8lupQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/p>\n<\/figure>\n<p><\/body><\/div>\n<div data-ga=\"article-footer-author\">\n<h3>\n\t\t<a href=\"https:\/\/www.pcworld.com\/author\/gung\" rel=\"author\"><br \/>\n\t\tAuthor: Gordon Mah Ung<\/a>, Executive Editor\t\t<\/h3>\n<div>\n<div>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.pcworld.com\/wp-content\/uploads\/2023\/01\/gordon19__large__400x400-100530424-orig-3.jpg?quality=50&#038;strip=all&#038;w=150&#038;h=150&#038;crop=1\" height=\"125\" width=\"125\">\n\t\t\t\t<\/p>\n<p>One of founding fathers of hardcore tech reporting, Gordon has been covering PCs and components since 1998.<\/p>\n<\/p><\/div>\n<ul>\n<li>\n\t\t\t\t\t\t\t\t<a href=\"https:\/\/twitter.com\/gordonung\" title=\"Twitter\" target=\"_blank\" rel=\"noopener\"><svg viewBox=\"0 0 512 512\"><path d=\"M459.37 151.716c.325 4.548.325 9.097.325 13.645 0 138.72-105.583 298.558-298.558 298.558-59.452 0-114.68-17.219-161.137-47.106 8.447.974 16.568 1.299 25.34 1.299 49.055 0 94.213-16.568 130.274-44.832-46.132-.975-84.792-31.188-98.112-72.772 6.498.974 12.995 1.624 19.818 1.624 9.421 0 18.843-1.3 27.614-3.573-48.081-9.747-84.143-51.98-84.143-102.985v-1.299c13.969 7.797 30.214 12.67 47.431 13.319-28.264-18.843-46.781-51.005-46.781-87.391 0-19.492 5.197-37.36 14.294-52.954 51.655 63.675 129.3 105.258 216.365 109.807-1.624-7.797-2.599-15.918-2.599-24.04 0-57.828 46.782-104.934 104.934-104.934 30.213 0 57.502 12.67 76.67 33.137 23.715-4.548 46.456-13.32 66.599-25.34-7.798 24.366-24.366 44.833-46.132 57.827 21.117-2.273 41.584-8.122 60.426-16.243-14.292 20.791-32.161 39.308-52.628 54.253z\" \/><\/svg><\/a>\n\t\t\t\t\t\t\t<\/li>\n<\/ul><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<p>\t<\/main><\/p>\n<p><main id=\"primary\"><\/main><\/p>\n<\/div>\n<\/div>\n<p><a href=\"https:\/\/www.pcworld.com\/article\/1473126\/camm-the-future-of-laptop-memory-has-arrived.html\" class=\"button purchase\" rel=\"nofollow noopener\" target=\"_blank\">Read More<\/a><br \/>\n Diego Pecora<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Skip to content Image: Dell Goodbye, SO-DIMM: Memory overseer JEDEC will formally adopt the \u201cCAMM Common Spec\u201d as the next RAM module standard for laptops.
