The integrated DDR Memory Controllers (DDRMCs) support both DDR5 and LPDDR5
14
+
compact and extended memory interfaces. Versal NET DDR memory controller
15
+
has an optional ECC support which correct single bit ECC errors and detect
16
+
double bit ECC errors. It also has support for reporting other errors like
17
+
MMCM (Mixed-Mode Clock Manager) errors and General software errors.
