Using the large maximal current density and the small diameter of carbon nanotubes, a flash memory arrangement is proposed. It makes use of the spin sensitive transport through hybrid conductor junctions. This memory contains no moving mechanical part and a single layer’s theoretical information density can reach beyond 40 Gbit/cm2. It is easy to build a three-dimensional memory structure. Then, the theoretical capacity can reach beyond 1015 bit/cm3 (1000 Terrabit/cm3), which means that a memory with 1 cm area and 1 mm thickness could have about 10 TerraByte capacity.
