traces. The DDR Protocol Suite provides detailed information of what happened inside the
bank active state by presenting following information, refer to Figure 3.44.
The start and end time of bank activation
The active row address
Density of Read/Write by drawing a graph with specific color for each type in dif‐
ferent time divisions (*see note below)
The power down active state when the power down happens in active bank

Note:
* While calculations involving the numbers of Reads and Writes are used to display the relative
density of these commands during a shown period, the time intervals and durations of these
displayed regions are selected to allow a subjective view of the traffic. This is why the regions
change when zooming in and out.
