(or \u201cthe company\u201d, <span style=\"text-decoration: underline;\"><a href=\"https:\/\/www.skhynix.com\/eng\/main.do\" target=\"_blank\" rel=\"noopener noreferrer\">www.skhynix.com<\/a><\/span>) announced today that it has developed working samples of DDR5<span style=\"color: #ff0000;\">*<\/span> Multiplexer Combined Ranks<span style=\"color: #ff0000;\">*<\/span> (MCR) Dual In-line Memory Module, the world\u2019s fastest server DRAM product. The new product has been confirmed to operate at the data rate of minimum 8Gbps, and at least 80% faster than 4.8Gbps of the existing DDR5 products.<\/p>\n<p>MCR DIMM is an achievement coming from out-of-the-box thinking with an aim to improve the operation speed of DDR5. Challenging the prevailing concept that the operation speed of DDR5 relies on that of DRAM chip itself, engineers sought to find a way to improve the speed of modules instead of chips for development of the latest product.<\/p>\n<p>SK hynix designed the product in a way that enables simultaneous operation of two ranks by utilizing the data buffer<span style=\"color: #ff0000;\">*<\/span> installed onto the MCR DIMM based on Intel\u2019s MCR technology.<\/p>\n<p style=\"font-size: 14px; font-style: italic; color: #555;\"><span style=\"color: #ff0000;\">*<\/span>Double Data Rate (DDR), a DRAM standard mainly used for servers and client applications, has been developed up to the fifth generation. The MCR DIMM is a module product with multiple DRAM chips attached to the board and improved speed as a result of two ranks operating simultaneously.<br \/>\n<span style=\"color: #ff0000;\">*<\/span>Rank: A collection of basic transfer units of the data sent to CPU from DRAM module. A rank typically refers to 64 bytes of data to be transferred to central processing unit as a bundle.<br \/>\n<span style=\"color: #ff0000;\">*<\/span>Buffer: A component that optimizes signal transmission performance between DRAM and CPU. Mainly installed onto modules for servers requiring high performance and reliability.<\/p>\n<p>By enabling simultaneous operation of two ranks, MCR DIMM allows transmission of 128 bytes of data to CPU at once, compared with 64 bytes fetched generally in conventional DRAM module. An increase in the amount of data sent to the CPU each time supports the data transfer rate of minimum 8Gbps, twice as fast as a single DRAM.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-10397 aligncenter\" src=\"https:\/\/d18r0a86za96sg.cloudfront.net\/wp-content\/uploads\/2026\/05\/27172347\/sk-hynix_MCRDIMM_EN_221004.png\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" alt=\"\" width=\"1000\" height=\"563\" \/><\/p>\n<p>A close collaboration with business partners Intel and Renesas was key to success. The three companies worked together and cooperated throughout the process from the product design to verification.<\/p>\n<p>SK hynix\u2019s Head of DRAM Product Planning Sungsoo Ryu said that the achievement was possible thanks to convergence of different technologies. \u201cSK hynix\u2019s DRAM module-designing capabilities were met with Intel\u2019s excellence in Xeon processor and Renesas\u2019 buffer technology,\u201d Ryu said. \u201cFor a stable performance of MCR DIMM, smooth interactions between the data buffer and processor in and out of the module are essential.\u201d<\/p>\n<p>Data buffer transmits multiple signals coming from the module in the middle and server CPU accepts and handles the signals coming though the buffer.<\/p>\n<p>\u201cSK hynix delivered another technological evolution for DDR5 by developing the world\u2019s fastest MCR DIMM,\u201d Ryu said. \u201cOur efforts to find technological breakthroughs will continue as we seek to solidify our leadership in the server DRAM market.\u201d<\/p>\n<p>Dr. Dimitrios Ziakas, Vice President of Memory and IO Technologies at Intel, said that Intel and SK hynix are leading the way on memory innovation and the development of high performance, scalable DDR5 for servers, along with other key industry partners.<\/p>\n<p>\u201cThe technology brought forward comes from years of collaborative research between Intel and key industry partners to produce significant increases in deliverable bandwidth for Intel Xeon processors,\u201d he said. \u201cWe look forward to bringing this technology to future Intel Xeon processors and supporting standardization and multigenerational development efforts across the industry.\u201d<\/p>\n<p>Vice President and General Manager of Memory Interface Division at Renesas Sameer Kuppahalli said that Renesas\u2019 development of the data buffer is a culmination of three years of intensive effort spanning from concept to productization. \u201cWe\u2019re proud to partner with SK hynix and Intel in the endeavor to realize this technology into a compelling product,\u201d he said.<\/p>\n<p>SK hynix expects the market for the MCR DIMM to expand driven by high performance computing that will take advantage of the increased memory bandwidth.
