Semiconductor memory device, semiconductor memory system including the same, method of driving the semiconductor memory system

Abstract

A semiconductor memory device includes a resistive change memory device including a control circuit block and a plurality of memory decks electrically connected with the control circuit block. The semiconductor memory device includes a pattern generation block, a position correction block and a position decision block. The pattern generation block receives a row address, a column address and a deck selection signal to generate a plurality of pattern generation signals to select a plurality of memory cells in the memory deck in various patterns. The position correction block receives a temporary code for classifying the memory cells into a temporary near cell region and a temporary far cell region and for reflecting a position of the memory deck in the temporary code to output a correction code. The position decision block is configured to generate first to third reset signals to reset a near cell region, a middle cell region and a far cell region based on the pattern generation signals and the correction code.
