Processing in-memory (PIM) is an emerging technology poised to break the memory-wall in the conventional von Neumann architecture. PIM reduces data movement from the memory systems to the CPU by utilizing memory cells for logic computation. However, existing PIM designs do not support high precision computation (e.g., floating-point operations) essential for critical data-intensive applications. Furthermore, PIM architectures require complex control module and costly peripheral circuits to harness the full potential of in-memory computation. These peripherals and control modules usually suffer from scalability and efficiency issues.

Hence, in this paper, we explore the analog properties of the resistive random access memory (RRAM) crossbar and propose a scalable RRAM-based in-memory floating-point computation architeture (RIME). RIME uses single-cycle NOR, NAND, and Minority logic to achieve …
