WRITE DRIVER, RESISTIBILITY MEMORY APPARATUS AND OPERATION METHOD THEREOF

摘要

According to an embodiment of the present invention, a write driver determines a magnitude and an application time of a pre-emphasis current pulse in response to control codes set in accordance with parasitic components existing on a path from the write driver to a program target cell and a resistance value of the program target cell, and adds a pre-emphasis current to a preset program current to supply the preset program current to a memory circuit unit in a program mode.
