One of the M-RAM block’s horizontal sides drive the address and control
signal (clock, renwe, byteena, etc.) inputs. Typically, the horizontal side
closest to the device perimeter contains the interfaces. The one exception
is when two M-RAM blocks are paired next to each other. In this case, the
side of the M-RAM block opposite the common side of the two blocks
contains the input interface. The top and bottom sides of any M-RAM
block contain data input and output interfaces to the logic array. The top
side has 72 data inputs and 72 data outputs for port B, and the bottom side
has another 72 data inputs and 72 data outputs for port A.
