Abstract
A data refresh is indispensable for a semiconductor dynamic random access memory device, and electric charges are recycled from bit line pairs for a row of memory cell arrays to power supply lines for bit line drivers associated with the next row of memory cell arrays and from bit line pairs for the next row of memory cell arrays to power supply lines for the row of memory cell arrays, thereby reducing power consumption in the data refresh.
