Memory Modes
© December 2009
Altera Corporation
During a write operation, the behavior of the RAM outputs is configurable. If you
activate rden during a write operation, the RAM outputs show either the new data
being written or the old data at that address. If you perform a write operation with
rden deactivated, the RAM outputs retain the values they held during the most
recent active rden signal.
To choose the desired behavior, set the Read-During-Write option to either New Data
or Old Data in the RAM MegaWizard Plug-In Manager in the Quartus II software.
For more information about read-during-write mode, refer to

the q output by one clock cycle.
