+# EDAC
+
+EDAC (Error Detection and Correction) framework provides support for detecting and correcting memory errors on systems with ECC (Error-Correcting Code) memory or other error detection mechanism.
+
+Intel i10nm EDAC driver supports the Intel 10nm series server integrated memory controller.
+
+## Usage
+
+You can run the cases one by one, e.g. command
+
+```
+./intel_edac.sh -t check_edac_bus
+```
+You also can run the cases together with runtests command, e.g.
+
+```
+cd ..
+./runtests -f edac/tests -o logfile
+```
