Patent number: 8130581Abstract: The present invention provides a semiconductor memory device in which the number of write amplifiers is decreased by increasing the number of bit line pairs connected to one pair of common write data lines. Further, by decreasing the number of bit line pairs connected to one pair of common read data lines, parasitic capacitance connected to the pair of common read data lines is reduced and, accordingly, time in which the potential difference between the pair of common read data lines increases is shortened. Thus, while preventing enlargement of the chip layout area, read time can be shortened.Type: GrantFiled: October 26, 2010Date of Patent: March 6, 2012Assignee: Renesas Electronics CorporationInventors: Hajime Sato, Masao Shinozaki
