Abstract
One of the promising emerging nanotechnologies is the molecular quantum-dot cellular automata (QCA). A considerable amount of attention has been given to the 2D 2-dot QCA circuit designs and simulations at the bit level by Hook and Lee. The purpose of this paper is two-fold: (1) to introduce a new 3D QCA lattice structure, formed by 2-dot QCA cells, and (2) to present a word-level QCA NanoIC design method using this 3D 2-dot QCA architecture, which uses a slice of the lattice to implement one bit of the word data. For example, for an 8-bit word, there will be 8 slices of 2-dot QCA lattice embedded in the NanoIC.
