2.1.1. Selecting Your External Memory Device

Different memory types excel in different areas. As a first step in planning your external memory interface, you must determine the memory type that best meets the requirements of your system.
  1. Determine your requirements for the following:
    • bandwidth
    • speed
    • data capacity
    • latency
    • power consumption
  2. Compare your requirements to the specifications for available memory protocols to find the memory device appropriate for your application.
