NANOSCALE WIRE-BASED SUBLITHOGRAPHIC PROGRAMMABLE LOGIC ARRAYS

摘要

An apparatus and methods for a sublithographic programmable logic array (PLA) are disclosed. The apparatus allows combination of non-restoring, programmable junctions and fixed (non-programinable) restoration logic to implement any logic function or any finite-state machine. The methods disclosed teach how to integrate fixed, restoration logic at sublithographic scales along with programmable junctions. The methods further teach how to integrate addressing from the microscale so that the nanoscale crosspoint junctions can be programmed after fabrication.
