Graphit memory chips
"A graphite memory cell is composed of sheets of graphite deposited between two electrodes. The two-electrode design of graphitic memory differs from that of flash memory, which requires a "source," a "drain," and a "gate" to hold electric charge--essentially the bits of data. Because flash memory must store charge on the gates, which tend to leak, the cells wear out over time. "
Researchers have also been experimenting with graphene and carbon nanotubes, but manufacturing processes which involve these two components are considerably slower than graphite.
