Similar to all RAM blocks, M-RAM blocks can have different clocks on
their inputs and outputs. Either of the two clocks feeding the block can
clock M-RAM block registers (renwe, address, byte enable, datain, and
output registers). The output register can be bypassed. The six labclk
signals or local interconnect can drive the control signals for the A and B
ports of the M-RAM block. ALMs can also control the clock_a,
clock_b, renwe_a, renwe_b, clr_a, clr_b, clocken_a, and
clocken_b signals as shown in
The R4, R24, C4, and direct link interconnects from adjacent LABs on
either the right or left side drive the M-RAM block local interconnect. Up
to 16 direct link input connections to the M-RAM block are possible from
the left adjacent LABs and another 16 possible from the right adjacent
LAB. M-RAM block outputs can also connect to left and right LABs
through direct link interconnect.
