A memory controller can include a front end portion configured to interface with a host, a central controller portion configured to manage data, a back end portion configured to interface with memory devices. The memory controller can manage memory devices according to different protocols. For a first protocol, the memory device performs error correction operations and for a second protocol, the memory controller performs error correction operations. For the first protocol, error correction information, error detection information, and/or metadata is exchanged between the memory devices and the memory controller via data pins. For the second protocol, error correction information, error detection information, and/or metadata is exchanged between the memory devices and the memory controller via data mask inversion pins. The second protocol can have some features disabled that are enabled according to the first protocol, such as low-power features.
