After more than a year of treating DRAM and HBM as an existential emergency, Samsung's (KRX: 005930) Device Solutions division is reportedly unfreezing the R&D programs it parked to fight that fire. DigiTimes flagged the shift this morning, with the underlying Korean reporting pointing to four lanes restarting in parallel: 400+ layer V-NAND, compound semiconductors, advanced packaging, and substrates. The timing matters because it lines up with a possible 18-day union walkout starting May 21, which could complicate execution just as those commitments are being revived.
V10 has been Samsung's clearest answer to a NAND roadmap that suddenly looks more contested: SK Hynix (KRX: 000660) is shipping 321-layer parts, while Kioxia/SanDisk and YMTC are moving faster on the architectural side with CBA-class hybrid bonding. The V10 architecture is bonded vertical NAND, where the cell array and CMOS periphery are fabricated on separate wafers and then hybrid-bonded. Same family of techniques as Kioxia/SanDisk's CBA and YMTC's Xtacking, and it's how you get past 400 layers without the periphery cooking during the cell stack thermal budget. Samsung is claiming roughly 1.6x bit density per unit area versus the current CoP approach. V11 is on the roadmap for 2027 with a stated 50% I/O improvement.
The packaging and substrate revival is the more interesting half. Samsung Electro-Mechanics (KRX: 009150) has been pushing FOPLP and glass substrate work for over a year, and Samsung's foundry side reportedly omitted $7B of advanced packaging capex from the Taylor, Texas plan late last year when customers weren't lined up. Tesla (NASDAQ: TSLA) and Apple (NASDAQ: AAPL) orders since are reported to have changed that math. The “concrete planning stage” language in the Korean reporting suggests real capex is coming, not another announcement-of-an-announcement.
What this means for SSD buyers is mostly downstream and slow. Even on the optimistic path, V10 client drives don't materialize until late 2026 or 2027, and Samsung's consumer SSD lineup has been treading water on the 236-layer V8 generation while Kioxia BiCS8 and Micron's 276L have eaten the high-end controller pairings. A V10 client part with hybrid bonding would be the first real architectural reset Samsung has shipped in years.
