STARAN
STARAN might be the first commercially available computer designed around an associative memory. The STARAN computer was designed and built by Goodyear Aerospace Corporation. It is a Content Addressable Parallel Processor, a type of parallel processor which uses content addressable memory. STARAN is a single instruction, multiple data array processor with a 4x256 1-bit processing element computer. The STARAN machines became available in 1972.
Goodyear Aerospace later developed the MPP based on similar principles but with a larger and wider processor array.
