摘要： Methods and structure for fault tolerant Non Volatile Memory (NVM) devices are provided. Readings of selected memory cells are compared to two thresholds above and below a neutral value. Consistency of comparison outputs is used to determine a good or bad reading. Parity bit correction can be used to correct bad readings.

摘要： A Radio-Frequency Identification (RFID) transponder is provided. The RFID transponder may include a basic ID flag circuit having a VDD voltage node, an output voltage node, and a capacitor coupled to the VDD voltage node and the output voltage node to store an ID flag. The persistence duration of the state of the ID flag is controlled by maintaining a charge and leakage circuit. The charge and leakage circuit includes an NMOS device having a source, a drain and a gate, the source node of the NMOS device being coupled to the capacitor and the drain node of the NMOS device being coupled to a first CMOS inverter. The first CMOS inverter is powered by a regulated supply voltage such that the voltage on the capacitor is not dependent on the forward voltage drop of the NMOS device.
摘要翻译：提供射频识别（RFID）应答器。 RFID应答器可以包括具有VDD电压节点的基本ID标志电路，输出电压节点和耦合到VDD电压节点的电容器和输出电压节点以存储ID标志。通过维持充电和泄漏电路来控制ID标志的状态的持续持续时间。充电和泄漏电路包括具有源极，漏极和栅极的NMOS器件，NMOS器件的源极耦合到电容器，NMOS器件的漏极节点耦合到第一CMOS反相器。第一个CMOS反相器由稳压电源供电，使得电容上的电压不依赖于NMOS器件的正向压降。

摘要： An apparatus and method for synchronous communications using a serial data stream employs a housing with a controller and a back plane. The housing accepts one or more modules for interconnection with the back plane. The back plane distributes power to the modules and provides a communication link from the controller to each module. Each communication link includes a data out line, a data in line and a clock line, where each clock line is derived from one clock source.
