Samsung early on Friday revealed the world’s first 32 Gb DDR5 DRAM die. The brand new reminiscence die is made on the corporate’s 12 nm-class DRAM fabrication course of and never solely gives elevated density, but additionally lowers energy consumption. The chip will enable Samsung to construct file 1 TB RDIMMs for servers in addition to decrease prices of high-capacity reminiscence modules.
“With our 12nm-class 32 Gb DRAM, we’ve secured an answer that can allow DRAM modules of as much as 1 TB, permitting us to be ideally positioned to serve the rising want for high-capacity DRAM within the period of AI (Synthetic Intelligence) and large knowledge,” mentioned SangJoon Hwang, govt vice chairman of DRAM product & expertise at Samsung Electronics.
32 Gb reminiscence dies not solely allow Samsung to construct an everyday, single-rank 32 GB module for shopper PCs utilizing solely eight single-die reminiscence chips, however in addition they enable for larger capability DIMMs that weren’t beforehand doable. We’re speaking about 1 TB reminiscence modules utilizing 40 8-Hello 3DS reminiscence stacks based mostly on eight 32 Gb reminiscence gadgets. Such modules might sound overkill, however for synthetic intelligence (AI), Massive Information, and database servers, extra DRAM capability can simply be put to good use. Finally, 1TB RDIMMs would enable for as much as 12 TB of reminiscence in a single socket server (e.g. AMD’s EPYC 9004 platform), one thing that can not be performed now.
With reference to energy consumption, Samsung says that utilizing the brand new dies they’ll construct 128 GB DDR5 RDIMMs for servers that devour 10% much less energy than current-generation modules constructed round 16 Gb dies. This drop of energy consumption might be attributed to each 12 nm-class DRAM manufacturing node in addition to avoiding the usage of 3D stacked (3DS) chips that pack two 16 Gb dies right into a single bundle.
Samsung is just not disclosing the velocity bins of its 32 Gb reminiscence dies, however completed 16 Gb modules made on the identical 12 nm-class expertise provide a 7200 MT/s knowledge switch fee.
Samsung intends to start out mass manufacturing of 32 Gb reminiscence dies by the top of 2023, however for now the corporate is not detailing when it plans to supply completed chips to clients. it is possible that the corporate will begin with shopper PCs first, although whether or not that translasts into any value financial savings stays to be seen.
In any other case, for servers it normally takes some time for server platform builders and distributors to validate and qualify new reminiscence elements. So whereas Samsung has 1 TB RDIMMs in its future, it’s going to take a while earlier than we see them in delivery servers.
