A three-dimensional solid-state memory is formed from a plurality of bit
lines, a plurality of layers, a plurality of tree structures and a
plurality of plate lines. Bit lines extend in a first direction in a
first plane. Each layer includes an array of memory cells, such as
ferroelectric or hysteretic-resistor memory cells. Each tree structure
corresponds to a bit line, has a trunk portion and at least one branch
portion. The trunk portion of each tree structure extends from a
corresponding bit line, and each tree structure corresponds to a
plurality of layers. Each branch portion corresponds to at least one
layer and extends from the trunk portion of a tree structure. Plate lines
correspond to at least one layer and overlap the branch portion of each
tree structure in at least one row of tree structures at a plurality of
intersection regions.
