We successfully implemented a one-transistor (1T) ferroelectric field effect transistor (FeFET) eNVM into a 28nm gate-first super low power (28SLP) CMOS technology platform using two additional structural masks. The electrical baseline properties remain the same for the FeFET integration and the JTAG-controlled 64 kbit memory shows clearly separated states. High temperature retention up to 250 °C is demonstrated and endurance up to 10⁵ cycles was achieved. The FeFET unique properties make it the best candidate for eNVM solutions in sub-2x technologies for low-cost IoT applications.
