APPARATUS FOR DRIVING WORD LINE OF SEMICONDUCTOR MEMORY DEVICE AND METHOD THEREOF AT LOW VOLTAGE STABLY

摘要

PURPOSE: An apparatus for driving a word line of a semiconductor memory device and a method thereof are provided, which operate at a low voltage stably by preventing the word line from being selected during a write operation, by disabling a word line enable signal. CONSTITUTION: According to the apparatus for driving a word line of a semiconductor memory device controlled by a number of control signals including an address signal and a data signal and a write enable signal and a chip selection signal, a decoding unit(402) decodes the address signal and generates a decode signal to determine a memory cell to access. A pulse signal generation unit(404) generates a pulse signal in response to the control signal. A sensing signal generation unit(400) is enabled by one of the control signals, and generates a sensing signal disabled in response as the write enable signal is disabled. And a word line enable signal generation unit(406) generates a word line enable signal by receiving the pulse signal and the sensing signal and a decoding signal of the address.
