dual-port mode with unregistered outputs. Registering the outputs of the RAM
simply delays the q output by one clock cycle.
True dual-port mode supports any combination of two-port operations: two reads,
two writes, or one read and one write, at two different clock frequencies.
shows the Cyclone III device family true dual-port memory configuration.

Note to
(1) True dual-port memory supports input or output clock mode in addition to the independent clock mode shown.
The widest bit configuration of the M9K blocks in true dual-port mode is 512 × 16-bit
(18-bit with parity).
