The present disclosure provides a memory system for selecting from among a plurality of read retry routines based on metadata. The memory system can include one or more memory devices and a memory controller. The memory controller can also detect a failure of a read operation. The memory controller can also analyze a set of values that correspond to a set of effectors of the read operation. The memory controller can select one or more read retry routines from a plurality of read retry routines based on the analyzing. Each of the plurality of read retry routines can associated with a different effector from the set of effectors and a read voltage that corresponds to the different effector. The memory controller can also perform the selected one or more read retry routines at the portion of the one or more memory devices to negate the failure of the read operation.
