Consequently, a single device is locked into a specific operating mode, unable to achieve the flexible reconfiguration required for complex neural networks. Here we introduce a new device concept, a \u201cpolarity\u2010reconfigurable memristor\u201d capable of breaking this constraint by exploiting the complex polar\u2010order competition in the van der Waals ferrielectric CuCrP\n                    <jats:sub>2<\/jats:sub>\n                    S\n                    <jats:sub>6<\/jats:sub>\n                    . By dynamically tuning the balance among antiferroelectric (AFE), ferrielectric (FiE), and ferroelectric (FE) states near the phase boundary, the device reversibly inverts its resistive hysteresis, switching between clockwise (CW) and counter\u2010clockwise (CCW) modes. This reversal allows the same device to alternate between potentiation\u2010 and depression\u2010type synaptic plasticity. These results establish polar\u2010order competition as an effective route to achieve intrinsic polarity reconfigurability for memory and neuromorphic hardware.\n
