    摘要: A method of checking the operation of memory cells. A first group of memory cells and a second group of memory cells are provided. The first group of memory cells is tested and a first set of test results is obtained, and the first set of test results is stored in the second group of memory cells. The first set of test results is read from the second group of memory cells. The second group of memory cells is tested and a second set of test results is obtained. The second set of test results is stored in the first group of memory cells. The test results can be compressed before they are output. Errors can be corrected by using an error correction code or duplicate copies of the test results. The method allows a test device to be provided that does not have memory. The complexity of the test device is therefore advantageously reduced. An electronic circuit is provided that includes a first group of memory cells, a second group of memory cells, and a test device programmed such that the method can be performed.

    摘要翻译: 检查存储单元的操作的方法。 提供了第一组存储器单元和第二组存储单元。 测试第一组存储器单元并且获得第一组测试结果,并且将第一组测试结果存储在第二组存储器单元中。 从第二组存储单元读取第一组测试结果。 测试第二组记忆单元,并获得第二组测试结果。 第二组测试结果存储在第一组存储单元中。 测试结果可以在输出之前进行压缩。 可以通过使用纠错码或测试结果的副本来纠正错误。 该方法允许提供没有存储器的测试设备。 因此有利地减少了测试装置的复杂性。 提供一种电子电路,其包括第一组存储器单元,第二组存储器单元和被编程的测试装置,使得可以执行该方法。

    摘要: A traffic metering system for metering access to at least one metered segment, configured to receive requests from one or more vehicles announcing a destination and a requested arrival time, and to authorize the vehicles to enter a metered segment based on a schedule for the at least one metered segment. Vehicles configured for use in the metering network announce a request for destination and arrival time to the metering network and the metering network authorizes the vehicle to enter the metered segment based on a schedule for the at least one metered segment.
