A method, apparatus and system of a self-test output for high density BIST
are disclosed. In one embodiment, an integrated circuit includes one or
more memories, a BIST controller coupled to the one or more memories to
perform write operation and to receive a PASS/FAIL signal from each
embedded memory and one or more comparators coupled to the one or more
memories latch mutually identical outputted data coming from the memories
upon a rising edge of an ORDY signal. In addition, the comparators may
compare the latched mutually identical outputted data and output
associated PASS/FAIL signal to the BIST controller. The BIST controller
registers the received PASS/FAIL result upon receiving the PASS/FAIL
signal from the comparators. The integrated circuit may include output
registers coupled to the BIST controller and the comparators output a
data log substantially serially upon receiving a SHIFT/CLK signal from
the BIST controller.
