Abstract
An integrated test device reduces external wiring congestion to a memory. The integrated test device provides for separate decoder testing and debugging to find specific errors in the memory. The device also helps in reducing the complexity of the test of external BIST. Furthermore, the number of clock cycles required for the decoder testing for an N-address memory is reduced from 4N cycles to N clock cycles. Additionally, the access time for the memory is reduced as the test device is used as a pipelining device in normal operation mode.
