Memory Modes
TriMatrix memory blocks include input registers that synchronize writes
and output registers to pipeline designs and improve system
performance. M4K and M-RAM memory blocks offer a true dual-port
mode to support any combination of two-port operations: two reads, two
writes, or one read and one write at two different clock frequencies.
Figure 4–11
Figure 4–11. True Dual-Port Memory Configuration
In addition to true dual-port memory, the memory blocks support simple
dual-port and single-port RAM. Simple dual-port memory supports a
simultaneous read and write and can either read old data before the write

Memory Feature
See the DC & Switching Characteristics chapter of the Stratix GX Device Handbook,
Volume 1 for maximum performance information.
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 GX device must write to the dual-port memory once and then disable the
write-enable ports afterwards.
