MIT and ADI have built a 16-bit processor using CNTs. 10 million CNTs were used to form 14,702 CMOS CNT field-effect transistors (CNTFETs), arranged in 3,762 digital logic blocks, that together operated as a 16-bit processor. The chip can fetch 32-bit instructions from memory, has a RISC-V register file, and can read and write 16-bit data ...
