The AI memory super-cycle has a shadow story.
While headlines track HBM allocation and DDR5 contract resets, 2D NAND prices just spiked 2–3× in the corner of the market that powers automotive ECUs, factory PLCs, network switches, and medical devices.
What happened: Samsung announced MLC NAND end-of-life with final shipments in June 2026. Micron, SK hynix, and Kioxia capped legacy output. TrendForce projects worldwide MLC capacity dropping ~42% YoY in 2026.
What's filling the vacuum: Macronix Q1 2026 revenue +71% YoY, gross margin 40.8%, NAND revenue +382% YoY. Macronix moved customers from quarterly to monthly pricing. Winbond approved a record NT$42.1B 2026 capex and says capacity is booked through 2027.
Why it matters beyond embedded: legacy hardware residual values are inverting. Decommissioned switches, storage controllers, automation gear, and test instruments built ~2014–2022 are shifting from "candidate for shred" to "candidate for harvest and resale."
