存算一体芯片发展现状、趋势与挑战

von Neumann architecture inherently faces “memory wall” and “power wall” bottlenecks, while the slowdown of Moore’s Law recently has further exacerbated the above bottlenecks. The emerging memory computing technology integrates data storage and computing through a collaborative innovation of the device–architecture–circuit–process, greatly reducing data movement and its related overheads. It is one of the most important techniques for breaking through the bottleneck of von Neumann architecture in the post-Moore era. Meanwhile, the in-memory computing chip achieves increased computability through a highly parallel computing paradigm, which can alleviate the pressure of process shrinkage. It is also an important strategic technology for our country in the artificial intelligence era. Following the discussions and proposals from the 347th “Shuangqing Forum (Youth)”, this paper addresses the current research status in the field of in-memory computing technology, summarizes its strategic significance for our country, looks forward to the key scientific problems and technical challenges that need to be addressed in the future, and provides further development trends and suggestions in this field.
