  • Patent number: 8854079
    Abstract: A system on chip (SoC) has a nonvolatile memory array of n rows by m columns coupled to one or more of the core logic blocks. M is constrained to be an odd number. Each time a row of m data bits is written, parity is calculated using the m data bits. Before storing the parity bit, it is inverted. Each time a row is read, parity is checked to determine if a parity error is present in the recovered data bits. A boot operation is performed on the SoC when a parity error is detected.

  • Patent number: 8856601
    Abstract: This invention permits selectively bypasses serial scan chains. Constant or low toggle data is directed to the bypassed serial scan chain, thus reducing power consumption. The number and identity of serial scan chains bypassed during a particular test can be changed dynamically dependent upon the semiconductor process variations of a particular integrated circuit. This enables an optimal test to be preformed for integrated circuits having differing semiconductor process variations.

  • Patent number: 8854857
    Abstract: The invention is an electronic device including a ferroelectric random access memory (FRAM), a first supply voltage domain, a second supply voltage domain and a low drop output voltage regulator (LDO) receive a first supply voltage of the first supply voltage domain and providing a second supply voltage of the second supply voltage domain. The second supply voltage domain supplies the FRAM. The LDO switches between a first state providing and maintaining the second supply voltage of the second supply voltage domain and a second state providing a high impedance output to the second supply voltage domain. The electronic device switches the LDO from the first state to the second state in response to a failure of the first supply voltage domain.

  • Publication number: 20140292361
    Abstract: An electronic package having multiple pins may be tested in parallel for output short circuit current by simulating a direct short to ground by simultaneously connecting multiple output pins directly to ground in order to active a current limiter associated with each of the output pins. The pins are then connected to a resistive connection to ground via a set of resistors; the direct ground is then removed, such that the current limiter associated with each of the output pins remains activated. A voltage drop across each of the set of resistors is measured simultaneously.

  • Publication number: 20140292356
    Abstract: A first sensor detects whether an object is within a first region that surrounds the first sensor. A second sensor detects whether the object is within a second region that surrounds the second sensor. The first and second sensors are omnidirectional capacitive electrodes. In response to the first sensor detecting that the object is not within the first region, a device determines that the object is not proximate to a particular side of the first and second sensors. In response to the first sensor detecting that the object is within the first region, and the second sensor detecting that the object is within the second region, the device determines that the object is not proximate to the particular side. In response to the first sensor detecting that the object is within the first region, yet the second sensor detecting that the object is not within the second region, the device determines that the object is proximate to the particular side.
