Read Port
All memory blocks support simple dual-port mode. Simple dual-port mode allows
you to perform one-read and one-write operation to different locations at the same
time.
Figure 3–11. Arria II GX Simple Dual-Port Memory
Note to
(1) Simple dual-port RAM supports input and output clock mode in addition to the read and write clock mode shown.
Simple dual-port mode supports different read and write data widths (mixed width
support).
dual-port mode. MLABs do not have native support for mixed width operations. The
Quartus II software can implement mixed width memories in MLABs with more than
one MLAB.
In simple dual-port mode, M9K blocks support separate write-enable and read-enable
signals. Read-during-write operations to the same address can either output a don’t
care value or old data.
MLABs only support a write-enable signal. Read-during-write behavior for the
MLABs can be either don’t care or old data. The available choices depend on the
configuration of the MLAB.

would simply delay the q output by one clock cycle.
