• SK hynix develops its first DDR5 DRAM-based CXL pattern
• Expandable CXL reminiscence to safe the expertise accessibility by growth of devoted HMSDK
• SK hynix to increase the CXL reminiscence ecosystem whereas strengthening its presence within the next-gen reminiscence options market

———————————————————————————————————–

SK hynix Inc. (or “the corporate”, www.skhynix.com) has developed its first DDR5 DRAM-based CXL (Compute Categorical Hyperlink) reminiscence samples and strengthened its presence in next-generation reminiscence options market. The shape issue of the pattern is EDSFF (Enterprise & Information Middle Commonplace Kind Issue) E3.S and it helps PCIe 5.0 x8 Lane, makes use of DDR5 customary DRAM and is provided with CXL controllers.

CXL¹⁾, which is predicated on PCIe (Peripheral Element Interconnect Categorical)²⁾, is a brand new standardized interface that helps enhance the effectivity of using CPUs, GPUs, accelerators, and reminiscence. SK hynix has participated within the CXL consortium from an early stage, and is trying to safe CXL reminiscence market management.

Expandable CXL Reminiscence to Start Mass Manufacturing in 2023

The important level of the CXL reminiscence market is expandability. The CXL reminiscence permits for versatile reminiscence growth in comparison with present server market, the place the reminiscence capability and efficiency are fastened as soon as the server platform is adopted. CXL additionally has excessive development potential as it’s an interface spotlighted for top efficiency computing programs equivalent to AI and large knowledge associated functions.

The primary CXL reminiscence machine developed by SK hynix is a 96GB product composed of 24Gb DDR5 DRAMs based mostly on 1anm, which is the newest tech node. The corporate expects excessive buyer satisfaction of this product with versatile configuration of bandwidth and capability expanded cost-efficiently.

“I see CXL as a brand new alternative to increase reminiscence and create a brand new market,” stated Uksong Kang, Head of DRAM Product Planning explaining SK hynix’s CXL reminiscence deployment technique. “We intention to mass-produce CXL reminiscence merchandise by 2023, and can proceed to develop cutting-edge DRAM applied sciences and superior packaging applied sciences to launch numerous CXL-based bandwidth/capability expandable reminiscence resolution merchandise.”

Varied Collaboration Plans to Develop the CXL Reminiscence Ecosystem

“Dell has been on the forefront of creating the CXL and EDSFF ecosystems, driving expertise requirements by way of the CXL and SNIA consortiums, and dealing carefully with our companions on CXL product necessities to satisfy future workload calls for. The SK hynix EDSFF E3.S type issue CXL reminiscence module is an instance of the modern merchandise that prospects will be capable of deploy to satisfy their rising reminiscence wants,” stated Stuart Berke, Vice President and Fellow at Dell’s Infrastructure Options Group.

Dr. Debendra Das Sharma, Intel Senior Fellow and co-GM of Reminiscence and I/O Applied sciences at Intel added, “CXL performs a vital function in extending reminiscence for knowledge heart programs to evolve. We look ahead to constructing and increasing the CXL reminiscence ecosystem, in addition to shortly creating expertise requirements by way of the CXL consortium, by collaborating with companions like SK hynix.”

“CXL is a key expertise that will likely be vital in optimizing reminiscence programs sooner or later, and we’re actively working with SK hynix in CXL reminiscence design and verification to advertise the speedy growth of the CXL reminiscence ecosystem,” stated Christopher Cox, Vice President of Expertise at Montage Applied sciences.

Securing Expertise Accessibility by Creating HMSDK devoted to CXL Reminiscence

SK hynix additionally developed the Heterogeneous Reminiscence Software program Improvement Equipment (HMSDK)³⁾ completely for CXL reminiscence units. The package will embody options to enhance system efficiency and monitor the programs whereas operating numerous workloads. The corporate plans to distribute it as an open supply within the fourth quarter of 2022. It’s anticipated that finish customers equivalent to software program builders will be capable of make the most of SK hynix’s CXL reminiscence extra successfully.

The corporate ready a separate pattern for analysis to assist prospects consider it with ease. As there’s at the moment no server which helps EDSFF E3.S x8 Lane, SK hynix changed the devoted samples’ EDSFF pins with PCIe to assist prospects set up the samples to current PCIe slots.

SK hynix is planning to exhibit the product in upcoming occasions, starting with Flash Reminiscence Summit in early August, Intel Innovation on the finish of September and Open Compute Venture (OCP) International Summit in October, whereas scheduling to exhibit a demo with HMSDK as properly. The corporate will actively deploy CXL reminiscence associated enterprise to offer prospects with the reminiscence merchandise they want in a well timed method.
