FAQ — Korean Semiconductor Equipment & IP
Q: Is OpenEdges Technology publicly traded? A: Yes. OpenEdges Technology is listed on KOSDAQ under ticker 394280. It is a Korean memory subsystem IP company licensing LPDDR6/5X Memory Controller, DDR PHY, and NoC interconnect to AI inference SoC fabless designers.
Q: Who uses Samsung Foundry? A: External customers include Tesla (FSD SoCs across HW3/HW4 generations), Tenstorrent (Wormhole, Blackhole), Qualcomm (modem and selected Snapdragon variants), Google (Pixel Tensor SoCs), Ambarella (CV3-AD ADAS), plus Korean and Asian fabless customers (Rebellions, FuriosaAI, DeepX, etc.). Captive workload comes from Samsung’s own System LSI division.
Q: Is Samsung Foundry the same as Samsung Electronics? A: Samsung Foundry is the contract-manufacturing division inside Samsung Electronics’ DS (Device Solutions) division. It is not a separately listed entity. Public-market exposure runs through Samsung Electronics (KOSPI: 005930).
Q: Is Neosem publicly traded? A: Yes — Neosem is listed on KOSDAQ under ticker 253590. It is a Korean memory test equipment maker positioned for the HBM and CXL test capacity cycle.
Q: Is Exicon publicly traded? A: Yes — Exicon is listed on KOSDAQ under ticker 092870. It is a Korean memory test equipment maker, comparable benchmark to Neosem.
Q: Is AP System publicly traded? A: Yes — AP System is listed on KOSDAQ. It is a Korean display equipment maker exposed to OLED capex cycles, including the 8.6G OLED build.
Q: What is SF2 / SF3 / SF4? A: Samsung Foundry’s process node naming. SF4 = 4nm-class, SF3 = 3nm-class, SF2 = 2nm-class. SF2 is the next major node target whose external customer roster will materially shape Samsung Foundry’s positioning vs TSMC through 2027–2028.
Q: Does Samsung Foundry compete with TSMC? A: Yes. Samsung is widely regarded as TSMC’s #2 challenger at advanced nodes. TSMC retains the bleeding-edge AI hyperscaler customer base; Samsung competes effectively in automotive, AI accelerator startups, mobile mid-tier, and Korean/Asian fabless segments.
Q: What is SOCAMM2? A: A new server memory module standard based on LPDDR5X, providing higher bandwidth (up to 153.6 GB/s per module) and ~70% better power efficiency vs DDR5 RDIMM. SK hynix has begun mass production of 192GB SOCAMM2 optimized for NVIDIA Vera Rubin. Samsung also makes SOCAMM2.
Q: What is the LPDDR6 SOCAMM2 standard? A: A JEDEC standard in development extending LPDDR6 into AI server memory modules (and a complementary LPDDR6 PIM standard for in-memory inference). This is the standardization vector that converts LPDDR from “mobile memory” into “AI inference server memory.”
