22.214.171.124. Bank Policy
Open bank resources are allocated dynamically as SDRAM burst transactions are scheduled. Bank allocation is requested automatically by the controller when an incoming transaction spans multiple SDRAM bursts or by the extended command interface. When a bank must be reallocated, the least‑recently‑used open bank is used as the replacement.
If the controller determines that the next pending command will cause the bank request to not be honored, the bank might be held open or closed depending on the pending operation. A request to close a bank with a pending operation in the timer bank pool to the same row address causes the bank to remain open. A request to leave a bank open with a pending command to the same bank but a different row address causes a precharge operation to occur.
