mode with unregistered outputs.
Arria II M9K and M144K blocks support true dual-port mode. Sometimes called
bidirectional dual-port, this mode allows you to perform any combination of two-port
operations: two reads, two writes, or one read and one write at two different clock
frequencies. True dual-port memory supports input and output clock mode in
addition to the independent clock mode.

The widest bit configuration of the M9K and M144K blocks in true dual-port mode
are:
■
■
Wider configurations 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, its maximum width equals half of the total
number of output drivers.
M9K: 512 × 16-bit (or 512 × 18-bit with parity)
M144K: 4K × 32-bit (or 4K × 36-bit with parity)
