Call Notes: Memory & NAND Market Update (Dec 2025)

Just before the Holiday break, I participated in an advisory session on the current state of the memory and NAND market, which is experiencing a marked upturn driven by constrained supply of legacy DRAM products and surging demand from higher-margin products like HBM and DDR5.

Here I’m sharing some of the notes I used for that discussion.

Call Notes: Memory Market Supply Constraints and Rising Prices (Nov 2025)

Abstract image of earnings.

Legacy and mobile DRAM types, including DDR4 and LPDDR5X, face severely extended delivery lead times, while contract prices for DRAM and NAND flash are rising sharply. This is leaving Smartphone OEMs and SoC vendors with elevated memory cost burdens that threaten margins and will likely force higher device prices.

Call Notes: Q4 Semiconductor Tracker

Microsoft Azure Cobalt 100

We’re in a moment that’s less about individual chip performance and more about processing-at-scale. It’s all about sprawling AI racks, optics, interconnect, and custom silicon hungry for scale, speed, and a story.

Research Note: Marvell Solidifies CXL Leadership w/ Ecosystem-Wide Interoperability

Marvell CXL

The CXL ecosystem is moving quickly from concept to deployment as hyperscalers, OEMs, and chipmakers seek new ways to address the memory bottlenecks that limit AI, cloud, and high-performance computing workloads. In this environment, interoperability is not a checkbox—it is the foundation that determines how quickly new architectures can reach scale.

Research Note: Enfabrica ACF-S Millennium

Enfabrica ACS-F Millennium

First detailed at Hot Chips 2024, Enbrica recently announced that its ACF-S “Millennium” chip, which addresses the limitations of traditional networking hardware for AI and accelerated computing workloads, will be available to customers in calendar Q1 2025.
