MRAM In-memory computing macro for AI computing

The recent huge success of AI requires the development of dedicated H/W solutions for massive basic arithmetic operations – multiply and accumulation (MAC). Inmemory computing is one of the most progressive attempts in AI acceleration. The key embodiment of in-memory computing is the crossbar array of conductive memories. The crossbar array stores neural net weights in situ and performs MAC operations in an analog manner to significantly reduce power consumption. Here we innovate device and circuit solutions to develop the first MRAM crossbar array using Samsung 28-nm embedded MRAM CMOS technology.
