Micron's NAND Business is Crumbling

NAND memory chips, used in solid-state drives and smartphones for permanent data storage, make up about one-quarter of Micron's (NASDAQ: MU) revenue. Micron held a 12.3% share in the calendar third quarter, according to TrendForce, putting the company in fourth place. When the company reported its fiscal fourth-quarter results, it disclosed that NAND sales volumes were down by a low-20s percentage from the previous quarter, and that NAND average selling prices were down a mid-to-high single percentage.
