Company profile: SK hynix Memory Solutions Inc.
Company overview. SK hynix Memory Solutions Inc. (since 2018, "SK hynix memory solutions America Inc." / SKHMS America) is a wholly owned U.S. R&D subsidiary of SK hynix Inc., the South Korea–based memory maker (KRX: 000660; ~KRW 97.15 trillion / ~US$68 billion 2025 revenue, roughly 30,000–48,000 employees group-wide depending on source). The entity was formed in August 2012 when SK hynix acquired Link_A_Media Devices Corporation (LAMD, founded 2004), and is headquartered at 3103 North First Street, San Jose, California. Third-party estimates of SKHMS's own headcount vary widely (roughly 200–1,000); no official figure was found.
Products / operations. SKHMS is an R&D engineering center, not a fab or standalone product seller. It designs SSD controller system-on-chips, advanced NAND flash-management systems, and firmware for NAND-based storage spanning enterprise, client, and mobile segments — including SATA and PCIe/NVMe enterprise/client SSD controllers and eMMC/UFS controller IP used in SK hynix's memory and (via the Solidigm organization) SSD businesses.
Patent-litigation posture. This is an operating-company subsidiary, not an NPE. Its two tracked appearances are both against Netlist, Inc., a California memory-module maker: Netlist named it as a co-defendant in a patent-infringement suit filed August 31, 2016 in the Central District of California (Southern Division), and it appears as co-petitioner (with parent SK hynix Inc.) in inter partes review petitions filed December 30, 2016 at the PTAB. The split — one defendant-side suit and one plaintiff-side IPR petition — reflects a two-way dispute over validity and infringement rather than NPE-style assertion. The district court venue is C.D. Cal., not a plaintiff-friendly Texas forum.
Notable context. The tracked cases belong to a broader Netlist–SK hynix battle over server RDIMM/LRDIMM memory-module patents (e.g., U.S. Patent Nos. 8,756,364; 8,516,185; 8,001,434), pursued in parallel at the ITC (Investigation No. 337-TA-1023), which closed in January 2018 with a no-infringement determination in SK hynix's favor; additional Netlist suits followed in later years.
