Abstract
In an embodiment of the invention, a pipelined memory bank is tested by scanning test patterns into an integrated circuit. Test data is formed from the test patterns and shifted into a scan-in chain in the pipelined memory bank. The test data in the scan-in chain is launched into the inputs of the pipelined memory bank during a first clock cycle. Data from the outputs of the pipelined memory bank is captured in a scan-out chain during a second cycle where the time between the first and second clock cycles is equal to or greater than the read latency of the memory bank.
