Data storage system including interface device

A data storage system comprising:

• a controller coupled to a plurality of memory devices to control memory operations of the plurality of memory devices, and including a plurality of communication lanes;
• and
• an interface device configured to connect one or more of the plurality of communication lanes to a host device, the interface device comprising:
• one or more shared input terminals connectable to one or more shared lanes used by a plurality of host port types;
• one or more dedicated input terminals connectable to one or more dedicated lanes used by a specific host port type of the plurality of host port types;
• one or more second switch circuits coupled to the one or more shared input terminals;
• and
• one or more first switch circuits coupled to the one or more dedicated input terminals and the one or more second switch circuits,
• wherein input terminals of the one or more second switch circuits are configured to receive inputs from the one or more shared lanes and input terminals of the one or more first switch circuits are configured to receive inputs from at least one of the one or more shared lanes or the one or more dedicated lanes.
