Patent number: 6768663Abstract: A semiconductor device architecture (200) is disclosed. Like unit circuits (202), arranged in rows and columns, are coupled to lower conductive segments (204a-204h). The lower conductive segments (204a-204h) are arranged in an “open” configuration, allowing adjacent unit circuits (202) be accessed simultaneously. The lower conductive segments (204a-204h) are coupled to higher conductive segments (208a-208t) by reconnector circuits (210a and 210b). The higher conductive segments (208a-208t) are arranged into folded pairs (208a/208d, 208b/208e and 208c/208f) between differential-type amplifiers (212a and 212b). The reconnector circuits (210a and 210b) each have a reconnect configuration and a switch configuration. In a reconnect configuration, the reconnector circuits (210a and 210b) couple adjacent folded higher conductive segment pairs to one another.Type: GrantFiled: May 2, 2003Date of Patent: July 27, 2004Assignee: Texas Instruments IncorporatedInventor: Yoshihiro Ogata

Patent number: 5804478Abstract: A type of semiconductor device with a configuration characterized by the fact that an electroconductive film (90) is formed beforehand in connection to step (54a) of insulating film(54), and an electroconductive layer (63) with step from the aforementioned electroconductive film is coated to form the side contact of the memory cell.

Patent number: 5574693Abstract: A semiconductor memory device characterized by the fact that the disturb test time of the semiconductor memory device can be shortened, and the power consumption can be cut.In the disturb test for the semiconductor memory device in this invention, multiple word lines are selected at the same time with a prescribed interval corresponding to the element isolation layout. As the word lines are selected corresponding to the element isolating layout, the interference caused by the element isolation state can be excluded. Since multiple word lines are selected at the same time, the time of operation can be shortened. Since the word lines are maintained in the selected state while the sense amplifiers are not reset, there is no increase in the power consumption although multiple word lines are selected at the same time.Type: GrantFiled: June 7, 1995Date of Patent: November 12, 1996Assignee: Texas Instruments IncorporatedInventors: Takashi Inui, Kiyotaka Okuzawa, Yoshihiro Ogata

Patent number: 5514628Abstract: A process is disclosed herein for increasing yield in a semiconductor circuity having redundant circuitry for replacing defective normal circuitry in the semiconductor integrated circuit. In the first step, an insufficient sinter operation (50) is carried out in a hydrogen atmosphere at a temperature of less than 350.degree. C. At this temperature, no significant change will be seen in the interface trap density. Thereafter, the integrated circuit is tested (54,56) and the defective normal circuitry then is replaced (58) with the redundant circuitry. The integrated circuit is then subjected to a sufficient sinter operation (64) which is an operation wherein the substrate is disposed at a temperature between 350.degree. C.-500.degree. C. for more than 30 minutes. This sufficient sinter operation is performed in a hydrogen atmosphere, allowing dangling bonds at the interface to be terminated with hydrogen. Preferable, the optimal temperature for the sufficient sinter is approximately 400.degree. C.Type: GrantFiled: May 26, 1995Date of Patent: May 7, 1996Assignee: Texas Instruments IncorporatedInventors: Osaomi Enomoto, Yoichi Miyai, Yoshihiro Ogata, Yoshinobu Yoneoka
