Memory Modes
TriMatrix memory blocks include input registers that synchronize writes
and output registers to pipeline designs and improve system
performance. M4K and M-RAM memory blocks offer a true dual-port
mode to support any combination of two-port operations: two reads, two
writes, or one read and one write at two different clock frequencies.

Memory Feature
See
The M-RAM block does not support memory initializations. However, the
M-RAM block can emulate a ROM function using a dual-port RAM bock. The
Stratix device must write to the dual-port memory once and then disable the
write-enable ports afterwards.
Table 4–36
Table
Violating the setup or hold time on the address registers could
corrupt the memory contents. This applies to both read and
write operations.
