Patent number: 6853584Abstract: A non-volatile memory semiconductor device has a circuit to compensate for the variation in the data pattern to be programmed. The variation in the data patter creates a variation in the current requirement. The array receives a plurality of data pattern signals which affect the total amount of current flowing into a plurality of columns and into the memory array. A high voltage source generates an output which is supplied along a conducting path connected to the group of columns. A pass transistor is in the conducting path controlling the current flow in the conducting path. A current source has a first terminal and a second terminal with the first terminal connected to the output of the high voltage generator and the second terminal connected to the gate of the pass transistor. A plurality of current sources are collectively connected to a node.Type: GrantFiled: May 2, 2003Date of Patent: February 8, 2005Assignee: Silicon Storage Technology, Inc.Inventors: Hung Q.

Patent number: 6849717Abstract: Nematodes, such as Caenorhabditis elegans, that express mutant and wild-type orthologs of human genes involved in polycystic kidney diseases (PKDs), are used to study the functions of the proteins encoded by the genes, to screen for other genes involved in the diseases, to identify mutations involved in the diseases, and to screen for drugs that affect PKD. Behaviors controlled by the action of the genes or gene products are identified and used in the assays. Hence an animal model is provided that permits study of the etiology of polycystic kidney disease and provides a tool to identify the genes involved in the disease pathway, and to identify compounds that may be used to treat or alter the disease progression, lessen its severity or ameliorate symptoms. The nematode genes that encode protein products, mutants of the genes, vectors that contain the genes and mutant genes and nematode strains that contain the vectors are also provided.Type: GrantFiled: September 5, 2000Date of Patent: February 1, 2005Assignee: California Institute of TechnologyInventors: Paul W.

Patent number: 6850793Abstract: In addition to the known MT (magnetization transfer) effect, an RMT (reverse MT) is newly found, which increases a detected MR signal strength. Both the MT and RMT effects can be explained with mutual interaction, such as phenomena of chemical exchange and/or cross relaxation, acted between a pool of water proton spins and another pool of macromolecule proton spins, for example, within an object. In order to enhance the MT or RMT effect, the frequency bandwidths of RF pulses, such as a 90° RF exciting pulse in a SE or FSE method, an inversion pulse in a FLAIR or fast FLAIR method, and others, are controlled. To enhance the MT effect, the bandwidth is controlled into a wider value (approx. more than 1250 Hz) than the normally (conventionally) used bandwidth, while to obtain the RMT effect, the bandwidth is controlled into a narrower value (approx. less than 1000 Hz) than the normally used bandwidth. Actively controlling the MT or RMT effect permits changed image contrast in MR imaging.Type: GrantFiled: March 2, 1999Date of Patent: February 1, 2005Assignee: Kabushiki Kaisha ToshibaInventors: Mitsue Miyazaki, Yoshimori Kassai

Patent number: 6839859Abstract: A clock non-synchronous type circuit performs data read operation on the basis of a read control signal. After a lapse of a predetermined delay time, read data is read out from the clock non-synchronous type circuit. The read data is latched in selected one of N latch circuits. A latch circuit is selected on the basis of a control signal instead of a clock signal. The control signal represents that read data is output from the clock non-synchronous type circuit, and hence a latch circuit is always selected after read data is output.Type: GrantFiled: September 27, 2001Date of Patent: January 4, 2005Assignee: Kabushiki Kaisha ToshibaInventors: Toshiyuki Kouchi, Masahiro Yoshihara, Hiroyuki Koinuma
