  • Method for built-in self-testing of ring-address FIFOs
    Patent number: 5513318
    Abstract: A dual-port, RAM-type ring-address FIFO (100) is tested by causing the FIFO to execute a composite test method comprised of set of interwoven steps (( 1 )-(31 ) or (1')-(25')). Upon execution, the steps of the composite method cause the FIFO (100) to manifest all possible memory, address and functional faults. The test method manifests faults by causing the FIFO (100) to alter the state of the various flags it normally sets and by altering the logic state of the data normally produced by the FIFO.
