single block of RAM ideal for data packet storage. The different-sized
blocks allow Stratix GX devices to efficiently support variable-sized
memory in designs.
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.
The memory address depths and output widths can be configured as
512 × 1, 256 × 2, 128 × 4, 64 × 8 (64 × 9 bits with parity), and 32 × 16
(32 × 18 bits with parity). Mixed-width configurations are also possible,
allowing different read and write widths.
