Memory devices are described along with manufacturing methods. An embodiment of a memory device as described herein includes a conductive bit line and a plurality of first electrodes. The memory device includes a plurality of insulating members, the insulating members having a thickness between a corresponding first electrode and a portion of the bit line acting as a second electrode. The memory device further includes an array of bridges of memory material having at least two solid phases, the bridges contacting respective first electrodes and extending across the corresponding insulating member to the bit line. The bridges define an inter-electrode path between the corresponding first electrode and the bit line defined by the thickness of the insulating member.
