55GCPS CAM using 5b analog flash

An analog CAM based on analog flash technology contains 256k computing nodes, organized into 4k rows of 64 synapses each, and is able to process in parallel the best match based on Manhattan distance between a 64-dimensional input vector and all 4b stored reference vectors. Each computing node is capable of storing and matching 5b data (1.28Mb total storage), making this CAM well suited to problems in pattern recognition that require limited precision. The chip uses analog flash technology for data storage, programmable on-chip references, and offset compensation.
