Reconfigurable logic cells based on dual gate MOSFET transistors (DG MOSFETs) including n inputs (A,B), n being greater than or equal to 2 and capable of performing at least four logic functions with which logical signals provided on the n inputs (A,B) may be processed. The cell contains, between the ground and the output (F) of the cell, at least one first branch including n dual gate N-type MOSFET transistors (M1,M2) in series and n−1 branches in parallel with the first branch, each provided with a dual gate N-type MOSFET transistor (M3), each of the logic functions corresponding to a given configuration of the cell. A specific set of control signals (C1,C2) is applied on the rear gates of at least one portion of the transistors (M2,M3), each control signal (C1,C2) being capable of setting the transistor (M2,M3) to a particular operating mode.
A reconfigurable logic cell comprising n inputs (A,B, . . . ), n being greater than or equal to 2, and capable of producing at least four logic functions with which logic signals provided on the n inputs (A,B, . . . ) may be processed, characterized in that it comprises, between the ground and the output (F) of the cell, at least one first branch including n dual gate N type MOSFET transistors (M1,M2, . . . ) in series and n−1 branches in parallel with the first branch, each provided with one dual gate N type MOSFET transistor (M3), each of the logic functions corresponding to a given configuration of the cell wherein a specific set of control signals (C1,C2, . . . ) is applied on the rear gates of at least one portion of the transistors (M2,M3, . . . ), each control signal (C1,C2, . . . ) being capable of setting the transistor (M2,M3, . . . ) to a particular operating mode, the n inputs (A,B, . . . ) being each connected on the front gate of one of the n transistors (M1,M2, . . . ) of the first branch, n−1 inputs (B) being also applied on the front gate of one (M3) of the n−1 transistors of the n−1 branches in parallel with the first branch.
