UltraScale+ architecture-based devices provide the capability to cascade the data out from one block RAM to the next block RAM serially. This enables the devices to create a deeper block RAM in a bottom-up fashion. When used in cascaded mode, the power consumption is considerably low compared to the block RAM used in non-cascaded mode.
