This chapter presents completed work in the design and implementation of memristor-based dividers. IMPLY, hybrid-CMOS, threshold-gate, and MAD approaches to binary-restoring, SRT, and Goldschmidt dividers are described and analyzed in terms of complexity and delay. Completed schematics and simulations are also given.
