Abstract

For application of PRAM to IoT devices, it is necessary to reduce write energy consumption of PRAM. In a sub-20nm PRAM technology, the optimization of heater material and structure was performed with the Sentaurus TCAD simulator, which notices that the TiN is more preferred than the Poly Si or W and the wall structure has better write energy efficiency than the confined structure. In addition, a novel heat-aware write method (HAW) is proposed, which controls the write current and voltage considering with the heat generated by the heater. With the HSPICE simulation using 0.25- μ m industry-compatible model, PRAM cell achieves the write energy improvement by 22%, 19%, and 36% in the case of the wall structure with TiN, the proposed HAW, and both, respectively.
