ROM Mode
All Stratix III TriMatrix memory blocks support ROM mode. A memory
initialization file (.mif) initializes the ROM contents of these blocks. The
address lines of the ROM are registered on M9K and M144K blocks, but
can be unregistered on MLABs. The outputs can be registered or
unregistered. Output registers can be asynchronously cleared. The ROM
read operation is identical to the read operation in the single-port RAM
configuration.
