CRAM: Collocated SRAM and DRAM With In-Memory Computing-Based Denoising and Filling for Neuromorphic Vision Sensors in 65 nm CMOS

This brief presents an energy-efficient collocated random access memory (CRAM) featuring charge based computing. A 9T bit-cell-based collocated DRAM and SRAM together with a 2-dimensional charge diffusion paths topology is used to store the input binary image data and compute locally. The computing network performs both denoising approximating a nearest-neighbor median filter for background noise and region filling for the fragmented objects....
