The invention and historical development of solid-state data storage span multiple decades and technological milestones rather than a single inventor. The first commercial solid-state drive (SSD) utilizing random-access memory (RAM) was created in 1976 by the Dataram Corporation, which introduced the "Bulk Core" system providing 2 megabytes of high-speed solid-state storage. Decades later, the modern flash-memory-based SSD architecture utilized universally today was shaped by pioneers in semiconductor manufacturing, flash memory engineering, and enterprise computing storage systems during the late 1980s and 1990s.
