MULTI-THRESHOLD FLASH NCL LOGIC CIRCUITRY WITH FLASH RESET

摘要

Multi-threshold flash Null Convention Logic (NCL) includes one or more high threshold voltage transistors within a flash NCL gate to reduce power consumption due to current leakage by transistors of the NCL gate. High-threshold voltage transistors may be added and/or may be used in place of one or more lower voltage threshold transistors of the NCL gate. A high-Vt device is included in the pull-up path to reduce power when the flash NCL logic gate is in the null state.

1. A logic circuit comprising:
a gate comprised of a plurality of transistors wherein the plurality of transistors provide for logical evaluation; a plurality of input lines, each having an asserted state and a null state, connected to the gate; a flash input line, having a first state and a second state, connected to the gate; an output line, having an asserted output state and a null output state, connected to the gate; a high-threshold transistor in a pull-up path that is used to reset the gate and set the output line into the null output state; and a second high-threshold transistor wherein the second high-threshold transistor is in a pull-up path for an output inverter and is gated based on the flash input line to the gate.
