The widest bit configuration of the M4K and M-RAM blocks in true dual-
port mode is 256
with parity), respectively. The 128
configuration of the M4K block and the 4K
configuration of the M-RAM block are unavailable because the number of
output drivers is equivalent to the maximum bit width of the respective
memory block. Because true dual-port RAM has outputs on two ports,
the maximum width of the true dual-port RAM equals half of the total
number of output drivers.
