An apparatus for managing a memory having a plurality of command/address pins is provided. The apparatus includes a command generating module and a control module. The command generating module generates a set of target commands. The set of target commands include a plurality of command groups. Each of the command groups corresponds to at least one command/address pin of the plurality of command/address pins. It is known that the memory accesses the set of target commands from the plurality of command/address pins at a target time point. The control module controls the command groups to have different transition times prior to the target time points when the command groups are transmitted on the plurality of command/address pins.
