ABSTRACT:
A semiconductor memory is disclosed having data lines divided lengthwise, which data lines cross word lines in a memory cell array and are selectively coupled to memory cells. A plurality of second data lines are arranged, one for each of predetermined groups of the data lines, to exchange data through first switches. Also one or more third data lines are arranged orthogonally to the second data lines to exchange data with the second data lines through second switches. Read/write controllers are coupled to the third data lines. Data is read and written for desired memory cells by selective drive of the word lines and the first and second switches.
