pMTJ STT-MRAM based Chiplets for Neuromorphic Computing

Avalanche Technology will offer MRAM chiplets based on its pMTJ STT-MRAM technology. Avalanchersquo;s MRAM chiplets use Generic MRAM Interface (GMI). The GMI is modeled on the widely-used HBM interface and is optimized for memory accesses. In addition to the memory interface, MRAM chiplets need a second interface to communicate with the rest of the chiplets in a multi-chiplet system. For example, Intelrsquo;s Advanced Interface Bus (AIB) protocol is in the forefront for direct chiplet-to-chiplet communication for DARPArsquo;s CHIPS (Common Heterogeneous Integration and Intellectual Property (IP) Reuse Strategies) program. To be used in AIB-based systems, Avalanchersquo;s MRAM chiplet will have an AIB interface and an adapter from the AIB to the HBM interface for the MRAM array.
