Abstract:
A semiconductor memory device comprises a plurality of input/output pads positioned on a semiconductor substrate and a plurality of memory cell arrays. Each of access times of the memory cell arrays is composed differently proportionally to the length of data passage between the input/output pads and the memory cell arrays. Therefore, a fast access memory area and a low access memory area can be provided within a single memory by having the asymmetric access times based on the physical distance to the input/output pad.
