摘要: An array built-in self test system has a scannable memory elements and a controller which, in combination, allow self test functions (e.g. test patterns, read/write access, and test sequences) to be modified without hardware changes to the test logic. Test sequence is controlled by logical test vectors, which can be changed, making the task of developing complex testing sequences relatively easy.
