The M9K memory block outputs of Cyclone IV devices power up to zero (cleared)
regardless of whether the output registers are used or bypassed. All M9K memory
blocks support initialization using a .mif. You can create .mifs in the Quartus II
software and specify their use using the RAM MegaWizard Plug-In Manager when
instantiating memory in your design. Even if memory is pre-initialized (for example,
using a .mif), it still powers up with its outputs cleared. Only the subsequent read
after power up outputs the pre-initialized values.
For more information about .mifs, refer to the
Quartus II
The M9K memory block clock enables of Cyclone IV devices allow you to control
clocking of each M9K memory block to reduce AC power consumption. Use the rden
signal to ensure that read operations only occur when necessary. If your design does
not require read-during-write, reduce power consumption by deasserting the rden
signal during write operations or any period when there are no memory operations.
The Quartus II software automatically powers down any unused M9K memory
blocks to save static power.
