Abstract
A resistive memory apparatus may include a memory cell array and a selective write circuit. The memory cell array may include a plurality of resistive memory cells coupled between a plurality of word lines and a plurality of bit lines. The selective write circuit may determine whether or not to perform a pre-read/comparison operation for a memory cell on which a next write operation is scheduled to be performed, based on a logic level of input data provided for a write operation. The selective write circuit may control the write operation for the memory cell array according to a determination result of the pre-read/comparison operation.
