Simple Dual-Port Block RAM
Each 18 Kb block and 36 Kb block can also be configured in a simple dual-port RAM mode.
In this mode, the block RAM port width doubles to 36 bits for the 18 Kb block RAM and
72 bits for the 36 Kb block RAM. In simple dual-port mode, independent Read and Write
operations can occur simultaneously, where port A is designated as the Read port and port
B as the Write port. When the Read and Write port access the same data location at the
same time, it is treated as a collision, similar to the port collision in true dual-port mode.
Readback through the configuration port is not supported in simple dual-port block RAM
mode.
