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:
A method and a configuration for the output of bit error tables from semiconductor devices are described. A test control unit reads the bit error table from the memory device following a request from the test apparatus. Then, the bit error tables are transmitted sequentially to the test apparatus for further processing.

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.

摘要:
Data signals are transmitted between a number of semiconductor chips which are connected to one another in a common chip package. For that a signal transmission arrangement is set up for a transmission of the signals via in each case one transmitting/receiving interface which is arranged at the chip ends of a power supply connection which connects the number of semiconductor chips.

摘要:
Addressable first units having ROM memory cells, for example word or bit lines, can be replaced by redundant second units having RAM memory cells. This has the advantage that the RAM memory cells can be realized with a smaller area than alternative PROM memory cells. The invention can be applied particularly advantageously to DROM memories.
