WRITE DRIVER CIRCUIT, SEMICONDUCTOR APPARATUS USING THE SAME AND MEMORY SYSTEM

摘要

A write driver circuit includes a write control unit and a write driver. The write control unit generates a write control current according to data for storage. The write driver generates a write current for writing the data in a memory cell in response to an address signal and the write control current. The write driver changes the amplitude of the write current according to the write control current and the address signal.
