There are several considerations that require your attention to ensure the success of your designs.
Implement External Conflict Resolution
In the true dual-port RAM mode, you can perform two write operations to the same memory location.
However, the memory blocks do not have internal conflict resolution circuitry.
To avoid unknown data being written to the address, implement external conflict resolution logic to the
memory block.
Customize Read-During-Write Behavior
Customize the read-during-write behavior of the memory blocks to suit your design requirements.
