10.2. Bank Management Efficiency

Bank management operation affects controller efficiency.

When a read operation reads changes from a row in a bank, it has an impact on efficiency, relative to the row in the bank remaining unchanged.

When a row in the bank is unchanged, the controller does not need to issue precharge and activate commands; by not issuing precharge and activate commands, the speed of the read operation is increased, resulting in better efficiency.

Similarly, if you do not switch between read and write frequently, the efficiency of your controller improves significantly.
