Abstract
A semiconductor memory device comprises a substrate, first and second lower electrode groups on the substrate and including a plurality of first and second lower electrodes, respectively, and first and second support patterns on side walls of and connecting each of the first and second lower electrodes, respectively. The first lower electrodes include a first center lower electrode arranged within a hexagonal shape defined by first edge lower electrodes. The second lower electrodes include a second center lower electrode arranged within a hexagonal shape defined by second edge lower electrodes. The first center lower electrode is spaced apart from each of the first edge lower electrodes in different first to third directions. The first support pattern is immediately adjacent to the second support pattern. The first center lower electrode is spaced apart from the second center lower electrode in a fourth direction different from the first to third directions.
