Patent JP-S62248195-A (JP)
Title: Semiconductor memory device
Inventor: TSURUOKA SHIGEO
IPC: G11C11/41
Filed: 1986-04-21
Abstract: PURPOSE:To speed up access time by dividing a memory cell arrays into plural memory cell groups in a row direction and connecting the word lines of the respective groups to a row decoder via two pieces of MOSFETs. CONSTITUTION:When the second word line WL 2, is selected by the row decoder WLD, the N-channel MOSFETs TRa1, TRb1 are turned on, and the first word lines WL1a and WL1b are rised to high level by a power source voltage VDD to turn off the N-channel MOSFETs TRa2 and TRb2. Consequently the information in memory cells are outputted to bit lines and selected by a column selection circuit. Since the word lines are divided, the parasitic capacitance of the word lines seen from the decoder decreases, and the accessing is speeded up.

Inventor: IWAMURA KEIICHI
IPC: G06T1/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To efficiently apply copyright protection or other means to various electronic watermark systems. SOLUTION: Each of supervisory agencies 101-104 uses a common watermark imbedding unit 105 to imbed information with high immunity to its own agency, to distributed input information as electronic watermark information. After that, each of the supervisory agencies 101-104 uses any of A-D watermark imbedding units 106-109 which adopt an electronic watermark system unique to each agency, to imbed other information to the information above. When a supervisory agency discovers illegally copied data on a network, the agency uses the common watermark imbedding unit 105 to extract the information imbedded by the common watermark imbedding unit 105. Thus, an agency imbedding the common watermark can be identified, and the resulting data is transmitted to the identified agency.  The agency, receiving the data, uses its own unique extracting unit to extract various information sets imbedded in the data. Thus, each agency has only to manage the imbedding unit and the extracting unit according to its own system, and without the need for provision of imbedding units and the extracting units adopting the diversified systems.
