Device Handbook, Volume 1 or the Stratix GX Device Family Data Sheet section of the Stratix GX Device Handbook,
Volume 1.
All registers shown have asynchronous clear ports, except when using the M-RAM. M-RAM blocks have
asynchronous clear ports on their output registers only.
Violating the setup or hold time on the address registers could corrupt the memory contents. This applies to both
read and write operations.

Single-Port Mode
The TriMatrix memory blocks can implement single-port clock mode for
single-port memory mode. Single-port mode is used when simultaneous
reads and writes are not required. See
memory block can support up to two single-port mode RAM blocks in
M4K blocks.
When instantiating TriMatrix memory you must understand the various
features that set it apart from other memory architectures. The following
sections describe some of the important attributes and functionality of
TriMatrix memory.
