A semiconductor memory for maintaining a word line driving voltage includes a cell array and a sense amplifier adjacent to the cell array. A dummy cell is formed at a peripheral portion of the cell array in such a manner that a dummy bit line and a word line intersect. A control circuit switches the...http://www.google.com.tw/patents/US7796452?utm_source=gb-gplus-share專利 US7796452 - Semiconductor memory device maintaining word line driving voltage
