The conference was held April 25-30 in a virtual format.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe title of the award-winning paper is \u0026ldquo;A 40nm 100Kb 118.44TOPS\/W Ternary-weight Compute-in-Memory RRAM Macro with Voltage-sensing Read and Write Verification for Reliable Multi-bit RRAM Operation.\u0026rdquo; The explosive growth of memory-centric workloads, from artificial intelligence to graph processing to data-analytics, has necessitated research and development of next-generation memory sub-systems. In particular, resistive RAM (RRAM) has emerged as a promising candidate because of its high density, high read speed, and non-volatility.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThis paper presented a 101.4Kb bit-bit encoding in an RRAM macro on a 40nm CMOS node, supporting compute-in-memory for ternary weight networks. A key innovation is the design and verification of a novel voltage-based read with active feedback that addresses a key technology challenge \u0026ndash; a low resistance ratio between the high resistance state and the low resistance state in high-endurance RRAM. The memory macro also features iterative write with verification to facilitate a reliable multi-bit encoding under a sense margin narrow margin.\u0026nbsp;This is one of the first demonstrations of reliable multi-bit encoding on RRAM in a foundry process on a scaled technology node. The fabrication was supported by the Taiwan Semiconductor Manufacturing Company\u0026rsquo;s (TSMC) university shuttle services.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ERaychowdhury leads the Integrated Circuits and Systems Research Lab (ICSRL), where this research was conducted in collaboration with TSMC.\u0026nbsp;He holds the Motorola Solutions Foundation Professorship in the Georgia Tech School of Electrical and Computer Engineering (ECE).
