The system-on-chip market for hard disk drives got a little tighter this week as LSI Corp. purchased the Infineon's HDD business unit for an undisclosed sum.
Infineon was never a major player in the industry, and apparently agreed to the deal so it could concentrate on its core power, microcontroller and communications businesses. For LSI, the acquisition provides it with Infineon's read channel and controller ASIC designs, plus a potentially lucrative license agreement for SoC and read channel designs from Hitachi Global Storage.
With Infineon out of the picture, the HDD silicon market is comprised of four major players: Marvell, LSI, Texas Instruments and STMicro. More than half the market is controlled by Marvell and LSI.
