Abstract
An example system in accordance with an aspect of the present disclosure is to use local error detection (LED) and global error correction (GEC) information to check data fidelity and correct an error. The LED is to be calculated per cache line segment of data associated with a rank of a memory. Data fidelity may be checked in response to a memory read operation, based on the LED information, to identify a presence of an error and the location of the error among cache line segments of the rank. The cache line segment having the error may be corrected based on the GEC information, in response to identifying the error.
