Scientists Build First Properly 3D-Stacked Processor, Run It At 1.4GHz

Stacked-up chip technology isn't new, but scientists at the University of Rochester have built the first properly-3D chip recently. Unlike previous attempts, with layered standard 2D chip-circuitry on top of similar layers, the new chip actually has components built into a 3D-matrix, with interconnects between… »9/16/08 7:10am9/16/08 7:10am
