Here, we introduce a parallel reservoir architecture realized within a single MEMS resonator via Blue Sideband Excitation (BSE). Unlike traditional approaches that rely on physical arrays or time-multiplexing, which often compromise structural complexity or processing speed—we utilize a unique combined-frequency driving scheme to simultaneously activate two distinct modes into their nonlinear regimes. This strategy effectively constructs two independent, parallel processing channels within a single device footprint, doubling the state-space dimensionality without increasing fabrication overhead. Built upon such a mechanism, it is demonstrated that fusing features from these co-existing modes can significantly enhance the reservoir computing ability of the proposed system for complex classification tasks. Therefore, the results suggest that exploiting the inherent multi-modal dynamics of continuous mechanical structures provides a scalable, wide-bandwidth solution for overcoming the dimensionality-bandwidth trade-off in next-generation computing hardware.
