hello
First of all, I would like to thank you for the great article.

I was just studying through it and had a question that prompted me to write.

As I understand it, parameters starting with t are time and parameters without t are clock cycles, correct? Or do parameters that start with t also mean clock cycle?

thank u

I might have missed something but.... In a read cycle the memory device drives the data onto the data bus after a rising edge of DQS... at what point does the ASIC sample it?
