Last week at the Embedded World 2012 event in Nuremberg, Germany, CogniMem Technologies demonstrated its 4096-neuron CogniBlox module that combines four of the companys 1K-neuron CM1K chips with 4Mbytes of Everspin MRAM. The MRAM is used to quickly load stored neuron patterns and to quickly save patterns for shifting among multiple recognition tasks on a real-time basis. CogniMem selected MRAM because of its fast read/write speed combined with its nonvolatility. A Lattice FPGA ties together the four CM1K neuron chips with the two MRAMs and the boards are stackable so that you can build a 1M-neuron system with 250 stacked boards. Such a system would deliver 0.13 petaflops with a power consumption of 500W.
