    Abstract: In an embodiment, a non-volatile memory device includes a memory array divided into a plurality of tiles, and a row decoder that includes main row decoding units associated to a respective group of tiles. The row decoded further includes local row decoding units, each associated to a respective tile for carrying out selection and biasing of corresponding word lines based on decoded address signals and biasing signals. Each local row decoding unit has logic-combination modules coupled to a set of word lines and include, for each word line, a pull-down stage for selecting a word line, and a pull-up stage. The pull-up stage is dynamically biased, alternatively, in a strong-biasing condition towards a tile-supply voltage when the word line is not selected, or in a weak-biasing condition when the word line is selected.

    Abstract: A pressure sensor device is to be positioned within a material where a mechanical parameter is measured. The pressure sensor device may include an IC having a ring oscillator with an inverter stage having first doped and second doped piezoresistor couples. Each piezoresistor couple may include two piezoresistors arranged orthogonal to one another with a same resistance value. Each piezoresistor couple may have first and second resistance values responsive to pressure. The IC may include an output interface coupled to the ring oscillator and configured to generate a pressure output signal based upon the first and second resistance values and indicative of pressure normal to the IC.

    Abstract: A safety system monitors faults in an embedded control system. The embedded control system is modeled to produce one or more model check values by calculating how many clock cycles will pass between an initialization time point and at least one event time point for a specific event. The initialization time point is a certain point in an initialization function of a scheduler in the embedded control system. The at least one event time point is an expected number of clock cycles to pass before a specific event occurs. In operation, the embedded control system is initialized, a current clock cycle counter value is retrieved at a certain point in the initialization, and either an occurrence or an absence of an occurrence of a scheduled event is recognized. A current clock cycle value is recorded upon the recognition, and a mathematic check value is produced from the clock cycle value stored at the certain point in the initialization and the clock cycle value recorded upon the recognition. Subsequently, the model check value is compared to the mathematic check value, and action is taken based on the comparison.

    Abstract translation: 安全系统监控嵌入式控制系统中的故障。 嵌入式控制系统被建模为通过计算在特定事件的初始化时间点和至少一个事件时间点之间经过多少个时钟周期来产生一个或多个模型检查值。 初始化时间点是嵌入式控制系统中的调度器的初始化功能中的某一点。 至少一个事件时间点是在特定事件发生之前要通过的期望数量的时钟周期。 在操作中,初始化嵌入式控制系统,在初始化中的某一点检索当前的时钟周期计数器值,并且识别调度事件的发生或不存在。 在识别时记录当前时钟周期值,并且从存储在初始化中的某一点的时钟周期值和在识别时记录的时钟周期值产生数学校验值。 随后,将模型检查值与数学检查值进行比较,并根据比较进行动作。
