  • Patent number: 7609558
    Abstract: A non-volatile semiconductor memory device includes a memory cell array having a plurality of multi-level memory cells connected in series. The plurality of multi-level memory cells forms a plurality of threshold distributions each of which corresponds to a status of a lower bit and a status of an upper bit, wherein a lower bit and an upper bit constitute a lower page and an upper page respectively. The status of the lower bit dichotomizes the threshold distributions into two groups and the status of the upper bit further dichotomizes each of two groups. When programming a memory cell of the upper page, higher potentials are applied to a non-selected word line adjacent to the selected word line than those applied to the non-selected word line when programming the memory cell of the lower page.

  • Patent number: 7594320
    Abstract: A solder resist comprising a thermosetting resin is printed on a surface of an insulating board (7) having a conductor circuit (6). The solder resist is then heat-cured to form an insulating film (1) having a low thermal expansion coefficient. A laser beam (2) is then applied to the portion of the insulating film in which an opening is to be formed, to burn off the same portion for forming an opening (10), whereby the conductor circuit (6) is exposed. This opening may be formed as a hole for conduction by forming a metal plating film on an inner surface thereof. It is preferable that an external connecting pad be formed so as to cover the opening. The film of coating of a metal is formed by using an electric plating lead, which is preferably cut off by a laser beam after the electric plating has finished.

  • Patent number: 7596075
    Abstract: Second digital information serving as copyright protection information can be stably and reliably read without any effect of a defect or pit missing on a disk-shaped recording medium. Second digital information is recorded onto a disk-shaped recording medium by wobbling a pit sequence recorded as a first signal. The second digital information is recorded so that a plurality of bits constituting the second digital information are allocated in a unit period of an identical sync signal contained in the first signal. During playback, the plurality of bits constituting the recorded second digital information are read a plurality of times every unit period of the sync signal, and information of the read bits is then integrated. Thus, information from a large number of wobbled pits across unit periods of a plurality of sync signals can be integrated to determine the bit values.
