What SkyHigh Memory does

SkyHigh Memory Limited, headquartered in Hong Kong, is a private joint venture between SK Hynix system ic (a wholly-owned subsidiary of SK Hynix) and Cypress Semiconductor, officially launched on April 1, 2019. The company designs, develops, manufactures, and markets non-volatile Flash Memory products — primarily SLC NAND (1Gb–16Gb), SPI NAND (1Gb–4Gb), e.MMC 5.1 managed NAND (2GB–64GB), and NAND Base MCP packages stacking SLC NAND with LPDDR4x DRAM. Its products are AEC-Q100 qualified with operating ranges up to +105°C and ONFI 1.0 compliant, targeting high-reliability embedded storage for automotive instrument clusters and infotainment, communications equipment, consumer electronics, and industrial/medical automation.

The company's business model is hardware sales of Flash Memory components through direct enterprise field sales organized into three regional teams covering APAC (Korea, Japan, India, Southeast Asia), EMEA, and the Americas. Manufacturing is asset-light, executed through strong collaborative partnerships with foundry and wafer partners that provide what the company describes as "unlimited" wafer capacity, drawing on SK Hynix's NAND manufacturing heritage (SK Hynix was a top 5 NAND supplier with over 10% share of the nearly $60 billion market in 2018) and Cypress/Spansion's product engineering and customer relationships. The cumulative team has shipped over 200 million NAND devices since 2012 across its target markets, with leadership composed almost entirely of veterans from SK Hynix and Cypress/Spansion.

SkyHigh Memory was created in response to opportunistic supply behavior during the 2018 NAND tightness cycle; its founding premise is to be a long-term, stable SLC NAND supplier offering product longevity, automotive-grade qualification, and consistent supply. The company has no disclosed independent venture or private equity funding — it operates as a JV-backed entity — and revenue is not publicly disclosed. Recent product direction includes the S8AxGG1 AI System Solution, an integrated SoC-plus-SPI NAND platform in an FBGA153 package targeting voice, sensor, and industrial AI edge applications.
