Abstract:
An integrated circuit, a system, and a method to integrate phase change memory and magnetoresistive random access memory within a same integrated circuit in a system. The integrated circuit may include an MRAM and a PCM. The MRAM may include an MRAM bottom electrode, an MRAM stack, and an MRAM top electrode. The PCM may include a PCM bottom electrode, where the PCM bottom electrode has a lower height than the MRAM bottom electrode, a phase change material, and a PCM top electrode.
