+title: Xilinx Versal DDRMC (Integrated DDR Memory Controller)
+
+maintainers:
+ - Shubhrajyoti Datta <shubhrajyoti.datta@amd.com>

+description:
+ The integrated DDR Memory Controllers (DDRMCs) support both DDR4 and LPDDR4/
+ 4X memory interfaces. Versal DDR memory controller has an optional ECC support
+ which correct single bit ECC errors and detect double bit ECC errors.
