We show the implementation of a ferroelectric field effect transistor (FeFET) based eNVM solution into a leading edge 22nm FDSOI CMOS technology. Memory windows of 1.5 V are demonstrated in aggressively scaled FeFET cells with an area as small as 0.025 μm2 At this point program/erase endurance cycles up to 105 are supported. Complex pattern are written into 32 MBit arrays using ultrafast program/erase pulses in a 10 ns range at 4.2 V. High temperature retention up to 300 °C is achieved. It makes FeFET based eNVM a viable choice for overall low-cost and low-power IoT applications in 22nm and beyond technology nodes.
