be slower than the value obtained with the BASIC test.
Next Phase:
If an error is detected during the EXTENSIVE test, the defective bit(s)
are identified and the display waits for your acknowledgment. Press
ESC after review to return to Standby Mode.
If no errors are detected - an OK test result is shown and you are
prompted to continue. Press
F1
to go to AUTO-LOOP for burn-in and
pattern tests. If the time delay passes with no user selection, the AUTO-
LOOP test is initiated.
As always, ESC terminates the test. Before you press
F1
to test your
next device, you can press
F4
to view the Test Log of the last tested
DUT. The Test Log provides you with a detailed list of all the test
results, including speed drift information.
Significance of a Successful EXTENSIVE Test:
The EXTENSIVE test verifies proper module operation under varying
voltage conditions. It will detect intermittent problems which are either
temperature dependent or resulting from adjacent cell interference. It
provides comparative scores of module performance. It further tests the
module with additional data patterns besides those utilized by the BASIC
test.
4.2.4 AUTO-LOOP TEST
During the AUTO-LOOP test, the module is endlessly tested with different
patterns of data bits, generated by different algorithms.
AUTO-LOOP is an excellent burn-in procedure, as it will continue
indefinitely until the user presses the Esc key. The time of the test, the
iteration (loop) number, applied voltage, module speed and cycle time,
module size, and mode type are displayed.
Some long tests like Self Refresh are incorporated into AUTO LOOP as
shown in the following screen:
