A system with memory includes a repeater architecture where memory connects to a host with one bandwidth, and repeats the channel with a lower bandwidth. A memory circuit includes a first group of signal lines to couple point-to-point between a first group of memory devices and a host device. The memory circuit includes a second group of signal lines to couple point-to-point between the first group of memory devices and a second group of memory devices. The second group of signal lines extends the memory channel to the second group of memory devices. The second group of signal lines includes fewer data signal lines than the first group of signal lines, to support a lower bandwidth than the first group of signal lines on the memory channel.
