Stratix IV memory block clock-enables allow you to control clocking of each memory
block to reduce AC power consumption. Use the read-enable signal to ensure that
read operations only occur when you need them to. If your design does not need
read-during-write, you can reduce your power consumption by de-asserting the
read-enable signal during write operations, or any period when no memory
operations occur.
The Quartus II software automatically places any unused memory blocks in
low-power mode to reduce static power.
