ROW DECODER IN MEMORY DEVICE

摘要

PURPOSE: A row decoder of a semiconductor memory device is provided to reduce an area of a chip design and to improve turn-on time of a word line by combining a plurality of word line drivers with one word time driver and immediately turning-on a word line after receiving an address indicating the word line from an address selector. CONSTITUTION: An address selector(50) selects a specific address, wherein a number of the address selector(50) is 64. A global row decoder(40) enables a specific word-line. The global row decoder(40) includes a word-line driver for driving a plurality of word-lines. The address selector(50) selectively connects the word-line driver to the specific word-line according to a certain row address signal. The word line driver is consist of a word-line boosting signal input terminal and a plurality of MOS transistors connected in serial between grounds.
