The Renesas multiport memory portfolio offers over 100 types of asynchronous and synchronous dual-ports, four-ports, and bank-switchable dual-ports, enabling simultaneous access with various arbitration techniques to prevent contention and system wait states. Options include on-chip hardware arbitration, semaphore token passing, and software arbitration for optimal memory selection. Multiport memory resolves bus matching issues across various widths (x8, x9, x16, x18, x36, up to x72 bits), accommodates mismatched voltage parts (1.8V, 2.5V, 3.3V, and 5V), and buffers speed mismatches (from DC to 10ns for asynchronous, up to 200MHz for synchronous devices). Densities range from 8Kb to 36Mb, catering to a broad spectrum of applications
