Abstract: Example embodiments provide a semiconductor memory device and method of forming a semiconductor memory device that may equalize load due to a coupling capacitance between a line and a component signal when the line intersects the component signal in a memory cell array. A line may intersect a memory cell region between a transmitting point (A) and a receiving point (B) of a signal. A line between the transmitting point (A) and the receiving point (B) may be bent at two portions of each of bit lines. Because areas where the line and the bit lines extend parallel to each other may be equal in dimension at each bit line, coupling capacitances between the line and the bit lines may be equalized. The read characteristic may not be affected by the coupling capacitances.

Abstract: A broadcast station that is a transmission device assigns an ID and a license transformation period to a license to be generated, and transmits to a terminal apparatus 102, in order to provide a digital right management system which can provide a protection for the rights of a provider while preventing an unauthorized obtainment of a license to be transmitted through a digital broadcast. The terminal apparatus 102 records a license import log including the license ID and license transformation period assigned to the license. Further, the terminal apparatus 102 controls a license obtainment in the case where the same license has been obtained by the time of obtaining the license. Furthermore, the license received by the terminal apparatus 102 is kept at least until the license transformation period expires.
