Stratix IV TriMatrix memory blocks allow you to implement fully synchronous SRAM
memory in multiple modes of operation. M9K and M144K blocks do not support
asynchronous memory (unregistered inputs). MLABs support asynchronous
(flow-through) read operations.
Depending on which TriMatrix memory block you target, you can use the following:

When using the memory blocks in ROM, single-port, simple dual-port, or true
dual-port mode, you can corrupt the memory contents if you violate the setup or
hold-time on any of the memory block input registers. This applies to both read and
write operations.
