Table 3–8. M144K Block Mixed-Width Configurations (True Dual-Port Mode)
In true dual-port mode, M9K and M144K blocks support separate write-enable and
read-enable signals. You can save power by keeping the read-enable signal low
(inactive) when not reading. Read-during-write operations to the same address can
either output “new data” at that location or “old data”.
In true dual-port mode, you can access any memory location at any time from either
port. When accessing the same memory location from both ports, you must avoid
possible write conflicts. A write conflict happens when you attempt to write to the
same address location from both ports at the same time. This results in unknown data
being stored to that address location. Conflict resolution circuitry is not built into the
Arria II memory blocks. You must handle address conflicts external to the RAM block.
