Patent number: 9240465Abstract: A semiconductor device has a vertical drain extended MOS transistor with deep trench structures to define a vertical drift region and at least one vertical drain contact region, separated from the vertical drift region by at least one instance of the deep trench structures. Dopants are implanted into the vertical drain contact regions and the semiconductor device is annealed so that the implanted dopants diffuse proximate to a bottom of the deep trench structures. The vertical drain contact regions make electrical contact to the proximate vertical drift region at the bottom of the intervening deep trench structure. At least one gate, body region and source region are formed above the drift region at, or proximate to, a top surface of a substrate of the semiconductor device. The deep trench structures are spaced so as to form RESURF regions for the drift region.Type: GrantFiled: August 7, 2015Date of Patent: January 19, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Marie Denison, Sameer Pendharkar, Guru Mathur

Patent number: 9239735Abstract: A statically scheduled processor compiler schedules a speculative load in the program before the data is needed. The compiler inserts a conditional instruction confirming or disaffirming the speculative load before the program behavior changes due to the speculative load. The condition is not based solely upon whether the speculative load address is correct but preferably includes dependence according to the original source code. The compiler may statically schedule two or more branches in parallel with orthogonal conditions.Type: GrantFiled: July 17, 2014Date of Patent: January 19, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Timothy D.

Patent number: 9240404Abstract: An embedded resistor structure in an integrated circuit that can be formed in a replacement gate high-k metal gate metal-oxide-semiconductor (MOS) technology process flow. The structure is formed by etching a trench into the substrate, either by removing a shallow trench isolation structure or by silicon etch at the desired location. Deposition of the dummy gate polysilicon layer fills the trench with polysilicon; the resistor polysilicon portion is protected from dummy gate polysilicon removal by a hard mask layer.

Patent number: 9236902Abstract: The present invention describes a method and apparatus for implementing a mobile receiver (10) that combats multiple access interference (MAI) in a code division multiple access (CDMA) spread spectrum system. Such capability is required by mobile receivers to support high data rate applications such as the ones provided by HSDPA and 1xTREME. A receiver (10) combining equalization and interference cancellation (IC), according to the invention, avoids the shortcomings of either equalization or IC and provides superior performance relative to prior art methodologies. The approach proposed by this invention for the operation of the mobile receiver is to first perform equalization (12) of the received signal (r) and then use the resulting decisions to perform IC. Combining equalization and IC yields a complexity that is smaller to that obtained by implementing conventional IC with a Rake receiver for the same performance.Type: GrantFiled: August 15, 2002Date of Patent: January 12, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventor: Aris Papasakellariou

Patent number: 9236096Abstract: An embodiment of the invention discloses a method for writing concurrently a binary logical value to one or more dummy memory cells in a dummy bit line pair. A diode is electrically connected between a power supply and the positive power supply line connected to the dummy memory cells. The binary logical value is then driven on to the dummy bit line pair. Next, one or more dummy word lines are driven to a logical high allowing selected dummy memory cells to be written with the binary logical value. After the selected dummy memory cells have been written to, the one or more dummy word lines are driven to a logical low. Next the diode is disabled by turning on a PFET connected between the power supply and the positive power supply line. Turning on the PFET also electrically connects the power supply to the positive power supply line.Type: GrantFiled: September 12, 2012Date of Patent: January 12, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Srinivasa Raghavan Sridhara, Raviprakash Suryanarayana Rao
