(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 the key features of its Heterogeneous Memory Software Development Kit (HMSDK)<span style=\"color: #ff0000;\">*<\/span>\u00a0are now available on Linux<span style=\"color: #ff0000;\">*<\/span>, the world\u2019s largest open source operating system.<\/p>\n<p style=\"font-size: 14px; font-style: italic; color: #555555; text-align: left;\"><span style=\"color: #ff0000;\">*<\/span><strong>Heterogeneous Memory Software Development Kit (HMSDK)<\/strong>: SK hynix\u2019s software development kit. It enables effective memory control, improving the performance of heterogeneous memory systems such as CXL memory.<br \/>\n<span style=\"color: #ff0000;\">*<\/span><strong>Linux<\/strong>: An operating system developed in 1991 by Linus Torvalds that has since expanded to become the world\u2019s largest open source operating system. Most operating systems for cloud systems and supercomputers, as well as smartphones, cars, and appliances, are built on Linux.<\/p>\n<p style=\"text-align: left;\">HMSDK is SK hynix\u2019s software for optimizing the operation of Compute Express Link (CXL)<span style=\"color: #ff0000;\">*<\/span>, which is gaining attention as a next-generation AI memory technology along with High Bandwidth Memory (HBM). Having received global recognition for HMSDK\u2019s performance, SK hynix is now integrating it with Linux. This accomplishment marks a significant milestone for the company as it highlights the company\u2019s competitiveness in software, adding to the recognition for its high-performance memory hardware such as HBM.<\/p>\n<p style=\"font-size: 14px; font-style: italic; color: #555555; text-align: left;\"><span style=\"color: #ff0000;\">*<\/span><strong>Compute Express Link (CXL)<\/strong>: A next-generation interface that efficiently connects CPU, GPU, memory, and other components in high-performance computing systems to support massive, ultra-fast computation. By applying CXL to existing memory modules, the capacity can be expanded by more than 10 times.<\/p>\n<p style=\"text-align: left;\">In the future, developers around the world working on Linux will be able to use SK hynix\u2019s technology as the industry standard for CXL memory, putting the company in an advantageous position for global collaboration on next-generation memory.<\/p>\n<p style=\"text-align: left;\">SK hynix\u2019s HMSDK enhances memory package\u2019s bandwidth by over 30% without modifying existing applications. It achieves this by selectively allocating memory based on the bandwidth between existing memory and expanded CXL memory. Additionally, the software improves performance by more than 12% over conventional systems through optimization based on access frequency, a feature which relocates frequently accessed data to faster memory.<\/p>\n<p style=\"text-align: left;\">The semiconductor industry anticipates full commercialization of CXL in the second half of 2024, coinciding with the release of the first server CPUs featuring the \u201cCXL 2.0\u201d specification. In preparation for this, SK hynix is currently validating CXL 2.0 memory in 96 GB and 128 GB capacities with customers. The company plans to begin mass production by the end of the year.<\/p>\n<p style=\"text-align: left;\">\u201cFor the development and spread of AI systems such as large language models (LLMs), it is now necessary to significantly improve not only semiconductors but also the level of system applications to support them,\u201d said Youngpyo Joo, Head of Software Solution at SK hynix. \u201cWith this Linux integration and collaboration, we will strive to improve our status as a total AI memory solutions provider by innovating technologies and expanding the ecosystem in this field.\u201d<\/p>\n<p style=\"text-align: left;\"><strong>About SK hynix Inc.<\/strong><\/p>\n<p style=\"text-align: left;\">SK hynix Inc., headquartered in Korea, is the world\u2019s top-tier semiconductor supplier offering Dynamic Random Access Memory chips (\u201cDRAM\u201d), flash memory chips (\u201cNAND flash\u201d), and CMOS Image Sensors (\u201cCIS\u201d) for a wide range of distinguished customers globally.
