M4K RAM Blocks
The M4K RAM block includes support for true dual-port RAM. The M4K
RAM block implements buffers for a wide variety of applications such as
storing processor code, implementing lookup schemes, and
implementing larger memory applications. Each block contains
4,608 RAM bits (including parity bits). M4K RAM blocks can be
configured in the following modes:
