One embodiment of the present disclosure describes a loopback network including a loopback datapath and a plurality of memory devices. The plurality of memory devices may include a first memory device coupled to a first trunk connector of the first loopback datapath via a first branch connector. The plurality of memory devices may also include a second memory device coupled to the first trunk connector of the first loopback datapath via a second branch connector. When data communicated with the first memory device is targeted by loopback parameters, the first memory device may output a first loopback data signal generated based at least in part on the first data to the first loopback datapath, and the second memory device may block output from the second memory device to the first loopback datapath.
