ABSTRACT:
A nano tube cell and a memory device using the same features a cross point cell using a capacitor and a PNPN nano tube switch to reduce the whole memory size. In the memory device, the unit nano tube cell comprising a capacitor and a PNPN nano tube switch which does not an additional gate control signal is located where a word line and a bit line are crossed, so that a cross point cell array is embodied. As a result, the whole chip size is reduced, and read and write operations are effectively improved.
