SanDisk Corporation is an American multinational company that designs, manufactures, and markets flash memory storage solutions. Founded in 1988 by Eli Harari, Sanjay Mehrotra, and Jack Yuan, the company is headquartered in Milpitas, California. SanDisk revolutionized the digital storage industry with its invention of the flash memory card and has since grown into one of the world’s largest providers of flash memory products. Its product portfolio includes a wide range of memory cards (such as SD, microSD, CompactFlash, and Memory Stick), USB flash drives, solid-state drives (SSDs), and embedded flash storage for mobile devices. Popular consumer product lines include SanDisk Ultra, SanDisk Extreme, and SanDisk Extreme Pro, each offering different levels of speed and durability for photography, gaming, and mobile storage. SanDisk also serves enterprise customers with high-performance SSDs and software-defined storage solutions for data centers. The company holds numerous patents in non-volatile memory technology, particularly in multi-level cell (MLC) and 3D NAND flash. SanDisk was listed on NASDAQ in November 1995 and remained publicly traded until its acquisition by Western Digital in 2016, after which it operates as a key flash storage brand within the Western Digital portfolio. Today, SanDisk maintains a global presence with manufacturing facilities, design centers, and sales offices worldwide, including a European headquarters in Dublin, Ireland, and joint ventures with Toshiba (now Kioxia) for flash memory production.
