TriMatrix memory consists of three types of RAM blocks: M512, M4K,
and M-RAM. Although these memory blocks are different, they can all
implement various types of memory with or without parity, including
true dual-port, simple dual-port, and single-port RAM, ROM, and first-in
first-out (FIFO) buffers.
