After all, SanDisk is a leading producer of flash memory and has captive manufacture through its joint venture with Toshiba. Yet, most market share rankings leave SanDisk out.
What’s going on here?
Owing to a long-standing convention SanDisk’s NAND chips aren’t counted since they are sold as “Systems” (with a controller.) The World Semiconductor Trade Statistics (WSTS) set that rule up, and most analysts Continue reading

Memory market statistics are compiled by numerous firms: The World Semiconductor Trade Statistics (WSTS) sold in the US and Europe by the Semiconductor Industry Association (SIA), Gartner Dataquest, IHS iSuppli, Web Feet, Semico, Forward Insights, and even DRAMexchange. Lots of entities use conflicting definitions of what is and what is not a chip. This causes each company’s numbers to differ from the others’.
In the case of WSTS, a chip that is packaged with another chip into a board becomes Continue reading
