  • LOW-POWER PHASE-CHANGE MEMORY TECHNOLOGY WITH INTERFACIAL THERMOELECTRIC HEATING ENHANCEMENT
    Publication number: 20220115590
    Abstract: A low-power phase-change memory (PCM) technology with interfacial thermoelectric heating (TEH) enhancement is provided. Embodiments described herein leverage a substantial, positive thermoelectric coefficient in PCM materials to generate additional heating or cooling at an interface with another material, enabling memory switching with a large reduction in current and power. Interfacial thermoelectric engineering is applied to a PCM cell using a special class of thermoelectric materials with large negative Seebeck coefficients (e.g., bismuth telluride (Bi2Te3), lead telluride (PbTe), lanthanum telluride (La3Te4), indium selenide (InSe), silicon-germanium (Si0.8Ge0.2)) to induce efficient heating at significantly lowered power and current.
