True Dual-Port Mode
Stratix IV M9K and M144K blocks support true dual-port mode. Sometimes called
bi-directional 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.

Figure 3–12. Stratix IV True Dual-Port Memory
Note to
(1) True dual-port memory supports input/output clock mode in addition to independent clock mode.
The widest bit configuration of the M9K and M144K blocks in true dual-port mode is
as follows:
■
■
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.
