Patent number: 7619464Abstract: An electronic data storage system uses current comparison to generate a voltage bias. In at least one embodiment, a voltage bias generator, that includes a current differential amplifier, generates a current that charges a load to a predetermined voltage bias level. The current comparison results in the comparison between two currents, Iref and Isaref. The current Isaref can be generated using components that match components in the load and memory circuits in the system. In one embodiment, multiple sense amplifiers represent the load. By using matched components, as physical characteristics of the load and memory circuits change, the current Isaref also changes. Thus, the voltage bias changes to match the changing characteristics of the load and memory circuits. The voltage bias generator can include a current booster that decreases the initial charging time of a reactive load.Type: GrantFiled: July 28, 2006Date of Patent: November 17, 2009Assignee: Freescale Semiconductor, Inc.Inventors: Jon S.

Patent number: 7616509Abstract: A power supply voltage for a memory on an integrated circuit is dynamically adjusted during the operating of the memory. The operating of the memory includes powering the memory at a supply voltage. A test memory of the integrated circuit is concurrently powered while operating the memory. The test memory and the memory each include bit cells of a first bit cell configuration type. A voltage level of the supply voltage is adjusted, while operating the memory, based on the testing of the test memory. The voltage level is adjusted with external variations to assume a value that guarantees no failed operation of the memory but also accurately minimizes the supply voltage. The system and method may be implemented with any type of memory. The memory and test memory may be physically implemented either separated or interspersed on the integrated circuit.Type: GrantFiled: July 13, 2007Date of Patent: November 10, 2009Assignee: Freescale Semiconductor, Inc.Inventors: Qadeer A.

Patent number: 7617437Abstract: A device for error correction includes a memory control module to disable error processing for a memory location depending on the state of a status indicator. The status indicator can be set so that error processing is disabled when valid error correction and detection information for the memory location is not available, such as after a reset or power-on event. In addition, the memory control module can promote partial write requests to full write requests when error processing is disabled to ensure that valid error detection and correction data is calculated for the memory location. By disabling error processing until valid error detection and correction information is available, the number of unnecessary or invalid error processing operations is reduced, thereby conserving device resources.Type: GrantFiled: February 21, 2006Date of Patent: November 10, 2009Assignee: Freescale Semiconductor, Inc.Inventor: William C.

Patent number: 7616676Abstract: An identification tag is provided in which radio frequency (RF) circuitry and ultrawide bandwidth (UWB) circuitry are both provided on the same tag, along with some UWB-RF interface circuitry.

The UWB circuitry then performs the necessary communication functions with a distant device and the power supply is again disconnected. In this way the power supply is only accessed when the UWB circuitry is needed and it's usable lifetime can be maximized.Type: GrantFiled: February 11, 2008Date of Patent: November 10, 2009Assignee: Freescale Semiconductor, Inc.Inventor: John W.

Patent number: 7615866Abstract: A semiconductor device has contact between the last interconnect layer and the bond pad that includes a barrier metal between the bond pad and the last interconnect layer. Both a passivation layer and a polyimide layer separate the last interconnect layer and the bond pad. The passivation layer is patterned to form a first opening to contact the last interconnect layer. The polyimide layer is also patterned to leave a second opening that is inside and thus smaller than the first opening through the passivation. The barrier layer is then deposited in contact with the last interconnect layer and bounded by the polyimide layer. The bond pad is then formed in contact with the barrier, and a wire bond is then made to the bond pad.Type: GrantFiled: May 23, 2006Date of Patent: November 10, 2009Assignee: Freescale Semiconductor, Inc.Inventors: James Jen-Ho Wang, Paul T.
