schliz writes "Harvard University researchers have assembled nanowires into tiny 'logic tiles' that can perform adder, subtractor, multiplexer, demultiplexer and clocked D-latch functions. While the 960-square-micrometre chips are not currently as dense as 32nm CMOS technology, the researchers say future versions could be up to 100 times more efficient than current electronics, and could yield low-power, application-specific 'nanocontrollers' for use in tiny embedded systems and biomedical devices."
