Overview
- Google unveiled TurboQuant this week, a method that compresses the key‑value cache used during AI inference by up to six times, which is the short‑term working memory that stores recent tokens to speed model responses.
- Shares in memory makers sank over the past five sessions, with Micron down about 20% and SanDisk off roughly 11% as investors reassessed AI memory demand.
- SanDisk disclosed a $1 billion purchase of 139 million Nanya shares for a 3.9% stake, alongside a supply deal to receive the Taiwanese firm’s DRAM products.
- Morgan Stanley kept overweight ratings on Micron and SanDisk and said TurboQuant reduces KV‑cache use rather than overall memory, adding that memory remains a bottleneck for AI builds.
- Micron reported record fiscal second‑quarter revenue of about $23 billion and very strong margins, yet its stock fell as worries over long‑term demand, heavy future capex, and broader macro risks weighed on sentiment.
