Abstract
A system includes a processing device, operatively coupled with a memory device, to perform operations including receiving a media access operation command designating a first memory location, and determining whether a first media access operation command designating the first memory location and a second media access operation designating a second memory location are synchronized, after determining that the first and second media access operation commands are not synchronized, determining that the media access operation command is an error flow recovery (ERF) read command, in response to determining that the media access operation command is an ERF read command, determining whether a head command of the first queue is blocked from execution, and in response to determining that the head command is unblocked from execution, servicing the ERF read command from a media buffer maintaining previously written ERF data.
