This work describes design process toward fully analogue binary memory where two coupled piecewise-linear (PWL) resistors are implemented using novel network topology with voltage gain amplifiers (VGA). These versatile active devices allow slopes of individual segments of ampere-voltage (AV) characteristics associated with PWL two-terminals to be electronically adjustable via external DC voltage. Numerical analysis of designed memory cell covers all mandatory parts: phase portraits, calculation of the largest Lyapunov exponent (LLE), basins of attraction for the typical strange attractors, and high resolution circuit-oriented bifurcation sequences. A transition from the stable states toward chaotic regime through metastability is proved via real measurement. The robustness of the generated chaotic attractors is verified by captured oscilloscope screenshots.
