  • Publication number: 20220399351
    Abstract: An approach for utilizing an IC (integrated circuit) that is capable of storing multi-bit in storage is disclosed. The approach leverages the use of multiple nanowires structures as channels in a gate of a transistor. The use of multiple nanowires as channels allows for different Vt (i.e., voltage of device) to be dependent on the thickness of the fe (ferroelectric layer) that surrounds each of the nanowire channels. Memory window is about 2d (thickness of a fe layer). Setting voltage is also proportional to the fe layer thickness. The Vt of the device is the superposition of the various fe layers. For example, if there are three channels with three different Fe layer (of varying thickness), then four memory states can be achieved. More states can be achieved based on the number of channels in the device.
