High-precision hyperdimensional computing enabled by in-memory computing using high-polarization ferroelectric Hf0.5Zr0.5O2 capacitors
We demonstrate high-precision hyperdimensional computing using an in-memory computing (IMC) architecture based on ferroelectric Hf0.5Zr0.5O2 (HZO) capacitors. By exploiting the high polarization charge density of CMOS back-end-compatible HZO, we achieved 32 well-separated and linearly programmable intermediate states i...
