The dual-port block RAMs have 4 KB of data storage capacity that is protected by error correction coding (ECC) for a total of 36 Kb per block RAM. The RAM can be configured as either one 36 Kb RAM, or two completely independent 18 Kb RAMs. The RAMs can be configured to operate in simple dual port mode (one read-only port and one write-only port) or true dual port mode (both ports have read and write interfaces). The block RAM can also be configure for single port mode. Each port has its own clock and address interface. The ports can be configured independently as 4K×9, 2K×18, 1K×36, or 512×72. The 512×72 mode requires simple dual port mode.

The block RAM is described in the Versal Adaptive SoC Memory Resources Architecture Manual (AM007).
