Sandisk works in the design, manufacture, and supply of storage solutions and devices built on advanced NAND flash technology. Its product range includes solid-state drives, embedded memory solutions, removable memory cards, and universal serial bus devices, along with the underlying wafers and components used to build them. Together these offerings cover storage needs from raw memory components through to finished, ready-to-use devices.
The company operates across this full range of storage formats, combining component-level manufacturing with consumer and embedded product lines rather than focusing on a single product type. This spread allows it to supply storage technology at different points, from wafers and components up through complete memory cards, drives, and USB devices.
Sandisk was founded on June 1, 1988. Its principal executive offices are located in Milpitas, California. The company's shares are listed on the NASDAQ under the ticker SNDK.
