Micron’s Automata Processor (AP) is a programmable silicon device, capable of performing high-speed, comprehensive search and analysis of complex, unstructured data streams. The AP is not a memory device, but it is memory based. It leverages the intrinsic parallelism of DRAM to answer questions about data as it is streamed across the chip.

Unlike a conventional CPU, the AP is a scalable, two-dimensional fabric comprised of thousands to millions of interconnected processing elements, each programmed to perform a targeted task or operation. Whereas conventional parallelism consists of a single instruction applied to many chunks of data, the AP focuses a vast number of instructions at a targeted problem, thereby delivering unprecedented performance.
