Abstract
A circuit for generating a write signal includes a pre-emphasis signal generator that receives location information of a to-be-programmed memory cell and generates a pre-emphasis signal depending on the location information of the to-be-programmed memory cell, and a write driver that generates a program signal corresponding to data to be programmed in the to-be-programmed memory cell. A write signal is generated by combining the program signal with the pre-emphasis signal supplied from the pre-emphasis signal generator, and the write signal output to the to-be-programmed memory cell.
