Abstract:
1. A method for driving data in a semiconductor memory device comprising a plurality of memory banks arranged at a cell region of a memory chip, each of the memory banks comprising a plurality of bank areas in which the number of bank areas corresponds to the number of the memory banks, a plurality of control pads sequentially arranged in a region between adjacent memory banks of the memory chip, and a plurality of I/O pads arranged in a peripheral region surrounding the memory banks, in which a predetermined number of I/O pads are allocated to each memory bank and are disposed near the corresponding memory bank in the peripheral region surrounding the memory banks, the method comprising the steps of: writing data to be stored in a bank area of a memory bank through the plurality of control pads and the predetermined number of I/O pads allocated to the corresponding memory bank; and reading data stored in a bank area of a memory bank through the plurality of control pads and the predetermined number of I/O pads allocated to the corresponding memory bank.
