1. A semiconductor memory device including at least one memory cell array, the memory cell array having memory cells disposed at intersections of rows and columns, the device comprising:
at least one decoder configured to select at least one of at least one row and at least one column associated with at least one memory cell; and
at least one signal delay controller configured to control a delay of an activation signal applied to the at least one of row and column by the at least one decoder in response to a block control signal based on at least one of a position of the at least one memory cell associated with the selected at least of one of row and column and a line loading capacitance value of the selected memory cell,
wherein the at least one signal delay controller equalizes access times for accessing memory cells regardless of a position of the memory cells within the memory cell array.
