A semiconductor memory device includes a memory cell array, a row decoder and a timing/voltage control circuit. The memory cell array is divided into a plurality of row blocks by one or more row block identity bits, and each of the of row blocks includes sub-array blocks arranged in a first direction. A row address includes the one or more row block identity bits. The row decoder activates a first word-line coupled to a first memory cell, activates a second word-line coupled to a second memory cell in response to the row address, and outputs a row block information signal. The timing/voltage control circuit adjusts at least one of an operation interval and an operation voltage of a memory operation on the first memory cell and the second memory cell according to a distance in a second direction crossing the first direction from a reference position, based on the row block information signal.
