This course offers a comprehensive journey into SDRAM controller design, starting with Day 1, where learners explore the fundamentals of DRAM cell operation, including how read and write operations work and why periodic refresh is mandatory, followed by an overview of the evolution of DRAM controller generations and the basics of first-generation controller design. Day 2 delves deeper into the architecture of second and third-generation DRAMs, introduces the internal block diagram of an SDRAM controller, and outlines the course design roadmap. On Day 3, participants learn the importance of SDRAM initialization, build flowcharts and FSMs, and implement the INIT module with complete testbench coding. Day 4 focuses on auto-refresh mechanisms, covering the design and verification of the refresh FSM and control logic. Day 5 explains how SDRAM enters low-power self-refresh mode, guiding learners through FSM design and testbench development for the self-refresh generator. Day 6 explores mode register programming, detailing the transactions and configuration of key parameters such as burst length and CAS latency. Day 7 covers write path design, highlighting DQM pin usage, write timing, FSM construction, and testbench verification. Day 8 addresses read path design by teaching SDRAM read timing and the development and testing of the read module. Day 9 introduces enhanced write control by addressing how to manage write operations during auto-refresh events and building a refresh-aware write controller. Finally, Day 10 brings all components together-INIT, AREF, SREF, WRITE, READ, and MODE-into a unified SDRAM controller design, preparing learners with the foundational knowledge required to transition confidently into DDR-based memory system design.
