Carbon nanotube (CNT)-based floating gate memories with high-k dielectrics were fabricated for low-power-consumption devices owing to the increase in the electric field intensity in the tunneling layer of memory devices. The memory with a high-k dielectric consisting of an Al2O3 layer achieved a larger hysteresis than the memory with a SiO2 layer. The results were well explained by simple electric field calculations using a cylindrical capacitor model. Furthermore, memory operation at a lower pulse voltage of 2 V or a shorter pulse width of 0.01 s was demonstrated on the basis of the memory with the Al2O3 layer. The results indicate that CNT-based floating gate memories with high-k dielectrics are promising candidates for low-power-consumption memories.
