Configurations
Table 2–3. TriMatrix Memory Features (Part 2 of 2)
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 II device must write to the dual-port memory once and then
disable the write-enable ports afterwards.
Memory Feature
Table
2–3:
Memory Block Size
TriMatrix memory provides three different memory sizes for efficient
application support. The Quartus II software automatically partitions the
user-defined memory into the embedded memory blocks using the most
efficient size combinations. You can also manually assign the memory to
a specific block size or a mixture of block sizes.
When applied to input registers, the asynchronous clear signal for the
TriMatrix embedded memory immediately clears the input registers.
However, the output of the memory block does not show the effects until
the next clock edge. When applied to output registers, the asynchronous
clear signal clears the output registers and the effects are seen
immediately.
