Carbon electronics research began at the end of the 20th century, but there were at least two nagging problems. The material must survive at the high temperatures needed in the circuit manufacturing process and in the data read/write process. Also, it must be pliable enough to quickly change states — from a zero to a one and back — yet stable enough to remain non-volatile when needed.
IBM says carbon, oxygen essential to advancing resistive memory - NiSystemsBlog
Scientists at IBM found that adding oxygen to carbon products makes resistive memory work at high temperatures. In 10 years, resistive memory could make flash memory and RAM obsolete
IBM researchers said they overcame stubborn challenges in building computer memory out of carbon instead of silicon, which could allow for systems that are faster and sturdier than conventional flash memory or RAM.
