ABSTRACT:
Each of N memory blocks of first to Nthstages includes a plurality of first and second driver units. The plurality of first and second driver units are respectively provided corresponding to one end and another end of a plurality of digit lines included in each memory block. Each of the first driver units in memory blocks before a selected memory block connects a corresponding digit line to a first voltage according to a voltage level on a digit line of the same row in a memory block of a previous stage. A second driver unit in the selected memory block connects a corresponding digit line to a second voltage in order to supply a data write current. In other words, digit lines in the memory blocks before the selected memory block are not used as current lines but as signal lines.
