This study demonstrates an MFIFM HZO capacitor for reservoir computing based on staggered polarization switching. Compared with a single-layer MFM HZO capacitor, the asymmetric MFIFM stack with two HZO layers separated by an ultrathin Al2O3 interlayer exhibits multi-peak switching current characteristics. These diverse transient responses improve the memory and nonlinear components required for reservoir computing, resulting in enhanced short-term memory and parity-check performance.
