We propose and evaluate an Optically Connected Memory (OCM) architecture that disaggregates the main memory from the computation nodes in data centers. OCM is based on micro-ring resonators (MRRs), and it does not require any modification to the DRAM memory modules. We calculate energy consumption from real photonic devices and integrate them into a system simulator to evaluate performance. Our results show that (1) OCM is ca","authors_text":"Alexander Gazman, Jorge Gonzalez, Keren Bergman, Lois Orosa, Maarten Hattink, Madeleine Glick, Mauricio G.
