It potentially operates with significantly lower power and writes faster than conventional flash memories. The Company spent years developing materials and processes with a promising combination of simplified structures for manufacturing with low power performance. The 4DS team is comprised of Silicon Valley veterans in material science, processing, equipment and memory device engineering. ..."
