TriMatrix Memory

Stratix Device Handbook, Volume 1
M-RAM Block
The largest TriMatrix memory block, the M-RAM block, is useful for
applications where a large volume of data must be stored on-chip. Each
block contains 589,824 RAM bits (including parity bits). The M-RAM
block can be configured in the following modes:
■
■
■
■
You cannot use an initialization file to initialize the contents of a M-RAM
block. All M-RAM block contents power up to an undefined value. Only
synchronous operation is supported in the M-RAM block, so all inputs
are registered. Output registers can be bypassed. The memory address
and output width can be configured as 64K × 8 (or 64K × 9 bits), 32K × 16
(or 32K × 18 bits), 16K × 32 (or 16K × 36 bits), 8K × 64 (or 8K × 72 bits), and
4K × 128 (or 4K × 144 bits). The 4K × 128 configuration is unavailable in
true dual-port mode because there are a total of 144 data output drivers
in the block. Mixed-width configurations are also possible, allowing
different read and write widths.
