Stratix GX Device Handbook, Volume 1
Similar to all RAM blocks, M-RAM blocks can have different clocks on
their inputs and outputs. All input registers—renwe, datain, address,
and byte enable registers—are clocked together from either of the two
clocks feeding the block. The output register can be bypassed. The eight
labclk signals or local interconnect can drive the control signals for the
A and B ports of the M-RAM block. LEs 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

Table 4–10. M-RAM Combined Byte Selection for ×144 Mode
Any combination of byte enables is possible.
Byte enables can be used in the same manner with 8-bit words, that is, in ×16, ×32,
×64, and ×128 modes.
