原英文标题：《CAMM: The future of laptop memory has arrived》
JEDEC has a SO-DIMM replacement in the works.
JEDEC正在开发SO-DIMM替代品。
Goodbye, SO-DIMM: Memory overseer JEDEC will formally adopt the “CAMM Common Spec” as the next RAM module standard for laptops.
再见，SO-DIMM：内存监督者JEDEC将正式采用“CAMM通用规范”作为笔记本电脑的下一个RAM模块标准。
JEDEC, the memory group that homologates RAM standards, is in the process of hammering out the new spec to replace the basic SO-DIMMs that have been in use for 25 years, according to JEDEC committee member, and Dell Senior Distinguished Engineer Tom Schnell.
JEDEC是认证RAM标准的内存组，据JEDEC委员会成员和戴尔高级杰出工程师Tom Schnell称，它正在敲定新规范，以取代已经使用了25年的基本SO-DIMM。
Schnell actually created the original CAMM—or Compression Attached Memory Module—design for Dell last year. JEDEC’s CAMM standard will be based on that CAMM design but is likely to be somewhat different as companies hammer it out.
Schnell实际上在去年为戴尔创建了最初的CAMM或压缩附加内存模块设计。JEDEC的CAMM标准将基于该CAMM设计，但随着各公司一同敲定规范，可能会有所不同。
While the adoption of new hardware standards can be fraught, with hand-wringing, foot-dragging, and all the friction of a negotiation among co-workers over where to get lunch, JEDEC seems to have managed it fairly easily.
虽然采用新的硬件标准可能会像同事之间关于在哪里吃午饭的谈判的所有摩擦一样令人担忧：手足无措且拖拖拉拉，但 JEDEC 似乎很容易做到。

In fact, Schnell said, the acceptance went over quite well with the 20 companies or so in the task group voting for it.
事实上，Schnell说，在工作组中投票支持它的公司达到20家左右，接受度相当不错。
“We have unanimous approval of the 0.5 spec,” Schnell told PCWorld. 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.
“我们一致批准了0.5规范，”Schnell告诉PCWorld。Schnell表示，JEDEC的目标是在2023年下半年完成1.0规范，基于CAMM的系统将在明年推出。
Who are the companies that voted for it? Schnell can’t say, as that’s 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.
谁是投票支持它的公司？Schnell不能说，因为这取决于每个成员，但集团涵盖了供应商的范围，从SoC到连接器，再到OEM，并且所有人都一致投票采用CAMM通用规范，没有异议。目前有332家公司在JEDEC上市，从苹果到中兴，每家公司都涉及不同行业的内存的不同方面。
For those who haven’t 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’s main appeal is that it enables higher memory density while also scaling to ever higher clock speeds.
对于那些还不了解 CAMM 的人，戴尔于 2022 年 4 月推出了其 CAMM 设计，旨在取代迄今为止大多数游戏和工作站笔记本电脑中使用的数十年前的 SO-DIMM 设计。CAMM 的主要吸引力在于它实现了更高的内存密度，同时还可扩展到更高的时钟速度。
Some of the motivation for expediency likely comes from the fast-approaching “brick wall” facing laptops when SO-DIMMs hit at DDR5/6400.
这一改变的冬季很可能来自于SO-DIMM规格来到DDR5-6400后面临的“频率墙”。
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.
Schnell表示，CAMM规范远未最终确定，但第一批JEDEC CAMM模块应该在SO-DIMM结束于6400时接管这一市场。

CAMM is not proprietary
CAMM 不是专有规范
When Dell first introduced CAMM, it was somewhat misunderstood as a proprietary spec that would “lock customers” into a design. Dell has said that’s never been its intention and the fast approval seems to vindicate that. Schnell addressed that initial concern, with the adoption underway.
当戴尔首次推出CAMM时，它在某种程度上被误解为一种专有规范，可以将客户“锁定”在设计中。戴尔曾表示，这从来都不是它的意图，快速批准似乎证实了这一点。Schnell表示JEDEC的采用化解了最初的问题。
“Dell is a huge company, we don’t keep the lights on because we get royalties for a patent,” he said. “We basically want to recover the cost of inventing it, and implementing it.”
“戴尔是一家大公司，我们不会因为获得专利的特许权使用费而保持光明，”他说。“我们基本上是想收回发明和实施它的成本。
Besides, going it alone is simply not how the PC world works.
此外，单打独斗根本不是PC世界的运作方式。
“We’re part of the PC industry and the PC industry is built out of an ecosystem of partners, suppliers all feeding in,” Schnell said. “Yes, Dell does great innovation of our own in our systems, but we also integrate a lot of innovations from a lot of people.”
“我们是PC行业的一部分，PC行业是由合作伙伴，供应商组成的生态系统建立起来的，”Schnell说。“是的，戴尔在我们的系统中进行了伟大的创新，但我们也整合了很多人的许多创新。
The future of CAMM
CAMM的未来
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’s also long been implemented only as soldered-on.
随着CAMM的敲定，Schnell确实为CAMM提供了一些可能的路径，因为它取代了SO-DIMM。他说，DDR6是一条显而易见的道路，但CAMM甚至可以在可更换模块上实现LPDDR6。LPDDR或低功耗DDR RAM长期以来一直是更小更薄的笔记本电脑以及省电手机的首选。长期以来，它只作为焊接实现。
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.
Schnell 预计 CAMM 版本可实现 LPDDR 的性能和功耗优势，但采用可更换和可升级的模块。随着JEDEC现在采用CAMM，未来越来越近。 |
