1. A method comprising: by computer program instructions on a computing device that controls a buffer, determining that a first copy of data stored at a first location within a plurality of memory cells of a memory component contains one or more errors; in response to determining that the first copy contains one or more errors, determining whether a backup cache within the buffer contains a second copy of the data; in response to determining that the backup cache does not contain the second copy of the data, determining whether the one or more errors contained in the first copy are correctable; and if the one or more errors are not correctable, creating a non-flushable entry within an error data queue (EDQ) and updating the computing device to use a location of the non-flushable entry within the EDQ instead of the first location within the plurality of memory cells.
