Design Methodology and Trends of SRAM-Based Compute-in-Memory Circuits

Processors based on conventional von Neumann architecture are approaching the memory wall, greatly limiting the development of high energy efficient AI edge devices. Compute-In-Memory (CIM) is a promising candidate to break the memory wall. This paper gives a survey of recent SRAM-CIMs with the focus on the computing methodology and performance of selected SRAM-CIM macros. The on-going trends of recent and further development of CIM technology are also discussed in this work.
