7.1.5. Timer Module

The timer module contains one DQ timer and eight bank timers (one per bank). The DQ timer tracks how often read and write requests can be issued, to avoid bus contention. The bank timers track the cycle time (tRC).

The 8-bit wide output bus of the bank timer indicates to the command issuing FSM whether each bank can be issued a read, write, or refresh command.
