摘要： Provided are a semiconductor memory device having a wordline enable signal line arrangement scheme, which can reduce VPP power consumption and can increase the speed of driving a sub-wordline, and a method of arranging wordline enable signal lines in the semiconductor memory device. In the semiconductor memory device, a wordline enable driver is arranged in a row decoder region outside a memory array region, and the wordline enable signal lines are formed of an uppermost metal layer among three metal layers constituting the semiconductor memory device. Each of the wordline enable signal lines is connected to a sub-wordline driver, rather than to a pair of sub-wordline drivers. In other words, the wordline enable signal lines vertically and horizontally extend forming an inverse L shape.

摘要： An LCD and a driving method thereof. A plurality of scan lines are divided into first-group scan lines and second-group scan lines. A scan signal is sequentially applied to the first-group scan lines in a first direction, and a scan signal is then sequentially applied to the second-group scan lines in a second direction. The first group includes odd scan lines and the second group includes even scan lines. Therefore, the brightness difference between the first and last lines can be reduced.

摘要： At least one refresh without scrubbing is performed on a corresponding portion of the memory device with a first frequency. In addition, at least one refresh with scrubbing is performed on a corresponding portion of the memory device with a second frequency less than the first frequency. Accordingly, refresh operations with data scrubbing are performed to prevent data error accumulation. Furthermore, refresh operations without data scrubbing are also performed to reduce undue power consumption from the data scrubbing.
