摘要： The disclosed invention provides a structure and method for detecting address line (e.g., wordline, bitline) memory failures. In one embodiment, the method and structure comprise generating an address signature, by re-encoding an internally generated address signal from activated elements (e.g., wordlines) inside a memory array. The regenerated address signature may be compared with a requested memory address location. If the regenerated address signature and memory location are equal than there is no error in the memory array, but if the regenerated address signature and memory location are equal than an error is present in the memory array. Accordingly, re-encoding an address signature provides a closed loop check that a wordline and/or bitline, that was actually activated in a memory array, was the correct requested wordline and/or bitline, that no other wordlines or bitlines were also triggered, and that the wordline and/or bitline is continuous.
摘要翻译：所公开的发明提供了用于检测地址线（例如，字线，位线）存储器故障的结构和方法。在一个实施例中，该方法和结构包括通过从存储器阵列内部的激活元件（例如，字线）重新编码内部产生的地址信号来生成地址签名。再生地址签名可以与请求的存储器地址位置进行比较。如果再生地址签名和存储器位置等于存储器阵列中没有错误，但是如果再生地址签名和存储器位置等于存储器阵列中存在错误。因此，对地址签名的重新编码提供闭环检查，即在存储器阵列中实际激活的字线和/或位线是正确请求的字线和/或位线，没有其他字线或位线也被触发，字线和/或位线是连续的。

摘要： Some embodiments of the present disclosure relate to a watchdog timer having an enhanced functionality that enables the watchdog timer to monitor a process flow of the microprocessor on a task-by-task basis that enables a simple output signal to be used to determine if the watchdog timer is malfunctioning. The watchdog timer has a state machine that increments a state variable from an initial value over a watchdog period. A deterministic service request, received from a microprocessor, controls operation of the watchdog timer. The deterministic service request has an indicator of a monitoring operation to be performed, a password, and an estimated state variable. A comparison element determines if the microprocessor is operating properly based upon a comparison of the received password to an expected password and the received estimated state variable to an actual state variable.
