A threshold logic-based reconfigurable logic element with a new programming technology

Abstract

We introduce a new reconfigurable logic element. Its operations are based on threshold logic and it can store its own configuration data. The element is composed of threshold gates which are implemented in a two-level feed-forward neuron MOS circuit. We present a effective method of switching and storing the values of two variable thresholds in a neuron MOS transistor so as to reconfigure the element without requiring any additional memory circuit or device. Circuit simulation results are provided to verify the correct operations of the reconfigurable element in the following four function modes: symmetric function modes with/without configuration data storage, and multiplexer function modes with/without control data storage.
