The Pentagon has long sought what the Wizard of Oz could not manufacture: a brain, or at least an electronic cognition machine that operates as closely as possible to the speed and efficiency of the human cortex. A coalition of IBM’s research institutes and several universities and government labs delivered a preliminary answer Thursday to that request: a 5.4-billion transistor chip with 1 million programmable neurons and 256 million synapses. The TrueNorth chip is the size of a postage stamp and is more than 1,000 times as energy efficient as a...
