Table 2–19. TriMatrix Memory Features (Part 2 of 2)
Violating the setup or hold time on the memory block address registers could corrupt memory contents. This
applies to both read and write operations.
Memory Feature
Table
2–19:
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.
M512 RAM Block
The M512 RAM block is a simple dual-port memory block and is useful
for implementing small FIFO buffers, DSP, and clock domain transfer
applications. Each block contains 576 RAM bits (including parity bits).
M512 RAM blocks can be configured in the following modes:

When configured as RAM or ROM, you can use an initialization file to
pre-load the memory contents.
