In modern embedded systems, high-speed memory is crucial for handling large amounts of data efficiently. DDR4 SDRAM provides a significant performance boost compared to older memory types, offering higher bandwidth and lower power consumption. The MT40A1G16TB-062E:F is a 4GB DDR4 SDRAM component with a data rate of 2400 Mbps, making it suitable for applications requiring fast data access and processing.

Objectives:

  1. Design a memory module using the MT40A1G16TB-062E:F DDR4 SDRAM.
  2. Implement a memory controller to interface with the DDR4 SDRAM.
  3. Integrate the memory module into an embedded system and test its performance.
  4. Evaluate the module's reliability and data handling capabilities.
