M4K RAM Blocks
The M4K RAM block includes support for true dual-port RAM. The M4K
RAM block is used to implement 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:
