The R4, C4, and direct link interconnects from adjacent LABs drive the
M4K RAM block local interconnect. The M4K RAM blocks can
communicate with LABs on either the left or right side through these row
resources or with LAB columns on either the right or left with the column
resources. Up to 16 direct link input connections to the M4K RAM block
are possible from the left adjacent LABs and another 16 possible from the
right adjacent LAB. M4K RAM block outputs can also connect to left and
right LABs through direct link interconnect.
