The relentless demand for AI compute has pushed high-bandwidth memory to its limits — not just in speed, but in the sheer complexity and cost of packaging it alongside processors. The international semiconductor standards body JEDEC has now answered with a significant architectural pivot: SPHBM4, a new standard that promises to untangle the packaging knot while preserving — and in some respects exceeding — the performance of today’s HBM4.

Samsung's Memory Business Hit With Fresh Patent Lawsuit Over HBM and DDR5

There’s a quiet but escalating legal war unfolding in the semiconductor industry’s most lucrative segment — and this time the battlefield extends far beyond Samsung. Netlist, a California-based memory technology firm, has filed a sweeping new complaint against the Korean giant with both the U.S. International Trade Commission (ITC) and the Eastern District of Texas federal court, alleging that Samsung’s high-bandwidth memory and DDR5 products infringe on two of its foundational patents. The ripple effects could reach every major player in the AI infrastructure stack, with Google, NVIDIA, Supermicro, and Broadcom all named as co-defendants.
