This description is directed to a dynamic random access memory (DRAM) array having a plurality of rows and a plurality of columns. The array further includes a plurality of cells, each of which are associated with one of the columns and one of the rows. Each cell includes a capacitor that is selectively coupled to a bit line of its associate column so as to share charge with the bit line when the cell is selected. There is a segmented word line circuit for each row, which is controllable to cause selection of only a portion of the cells in the row.
