Challenge Problems
Push your limits with challenges.
Question 1
Consider a DDR memory system with a CAS latency of 4 and a T_rfc of 64ms. If you have a system that requires 1000 refreshes per hour, will this system be able to maintain data integrity? Discuss the implications.
💡 Hint: Think of how refresh intervals relate to timing constraints.
Question 2
You've designed a DDR memory system and noticed that the performance has been subpar. With a logged CAS latency of 10, T_rp of 12ns, and T_rcd of 14ns, what adjustments would you consider making, and how?
💡 Hint: Consider how each parameter impacts overall latency.
