(color online) Synchronization results from simulation observation of drive (21)–(25) and response (26)–(29) memristor-based Chua chaotic systems: (a) (x₁₁ + 2x₂₁)(x₃₁ + 5x₄₁), (2y₁₁ + 4y₂₁ + y₃₁ + 2y₄₁) space; (b) (−x₁₂ + 2x₂₂)(x₃₂ + x₄₂), (3y₁₂ + y₂₂ − y₃₂ + 3y₄₂) space; (c) (2x₁₃ + 2x₂₃) (− x₃₃ − x₄₃), (2y₁₃ + 3y₂₃ + 2y₃₃ − y₄₃) space; (d) (x₁₄ + 2x₂₄)(2x₃₄ + x₄₄), (2y₁₄ − 2y₂₄ + 3y₃₄ + y₄₄) space.
