Abstract:
This disclosure concerns a memory including memory cell arrays including word lines extending in a first direction, bit lines extending in a second direction crossing the first direction, and memory cells provided to respectively correspond to cross-points in form of a lattice constituted by the word lines and the bit lines; sense amplifiers provided to respectively correspond to the bit lines and reading data stored in the memory cells; and bit line drivers provided to the bit lines and operating the bit lines when data is written to the memory cells, wherein the bit line drivers access the memory cells adjacent to a first memory cell diagonally with respect to the form of the lattice for writing the data to the adjacent memory cells during a data write operation without changing data stored in the memory cells adjacent to the first memory cell in the first and the second directions.
