Selecting TriMatrix Memory Blocks
The Quartus II software automatically partitions user-defined memory
into embedded memory blocks using the most efficient size
combinations. The memory can also be manually assigned to a specific
block size or a mixture of block sizes.

Pipeline & Flow-Through Modes
TriMatrix memory architecture implements synchronous (pipelined)
RAM by registering both the input and output signals to the RAM block.
All TriMatrix memory inputs are registered providing synchronous write
cycles. In synchronous operation, RAM generates its own self-timed
strobe write enable (wren) signal derived from the global or regional
clock. In contrast, a circuit using asynchronous RAM must generate the
RAM wren signal while ensuring its data and address signals meet setup
and hold time specifications relative to the wren signal. The output
registers can be bypassed.
In an asynchronous memory neither the input nor the output is
registered. While Stratix and Stratix GX devices do not support
asynchronous memory, they do support a flow-through read where the
output data is available during the clock cycle when the read address is
driven into it. Flow-through reading is possible in the simple and true
dual-port modes of the M512 and M4K blocks by clocking the read enable
and read address registers on the negative clock edge and bypassing the
output registers.
For more information, see AN 210: Converting Memory from Asynchronous
to Synchronous for Stratix & Stratix GX Devices.
Violating the setup or hold time on the address registers could
corrupt the memory contents. This applies to both read and
write operations.
