(2.2.4) Error Processing
When
the total error
is
zero, the system does not detect
an
error
in
the test.
On
the other hand, if the system detects
an
error, it displays the following error
message
on
the error
message field
and
continues the test.
"Memory error!
I"
If
the system detects
an
error, it displays the address, data,
and
relating
Ie
number where
the
error
occurs.
(2.3) Aging [Marching and
ADCOMP]
.
(2.3.1)
Outline
This
program
serves
as
an
aging
test
for
the memory.
It
alternately conducts marching test
and
address complement
test.
For details
of
the program,
see
Paragraphs (2.1) "Marching"
and (2.2) "Address Complement".
(2,3.2.) Operation
When
specifying this test, enter the proper data
to
prompts
displayed sequentially
as
shown
in
Figure
MEM-4.
(a)
Test
(a.l) Specification of Error Stop
Error
stop?
[0: Yes, 1:
NoJ
=
I\l
If
an
error
occurs while conducting the test, specify
whether
to
abort or continue the test.
(a.2) Confirmation of Test Execution
-------------------~-----
Test
start?
[0:
Yes,
1:
NoJ
=
I\l
Confirm whether
to
execute the test or not.
When entering
[[1
J],
the test can
be
conducted from
"Specification
of
Error
Stop" mentioned
in
(a.1).
On
the
other hand, when entering [[OJ],
the
system displays the
screen
as
shown
in
Figure
MEM-4
and starts the test.
The system
displays the current
area
and total
area
in
hexadecimal notation on the lower portion
of
the screen.
Test mode: Marching
Pass
count
[Ox]
=
~1\l~1\l
Current area [OxJ =
I\ll\ll\ll\ll\l
-
~I\ll\ll\ll\l
Total error
[Ox]
=
I\ll\ll\ll\l
The test mode represents the currently executing mode
(Marching, Address complement). The pass count repre-
sents the number
of
times
of
test pass.
The current
area
represents the
area
being tested
in
the unit
of
4
KB
physical address. The total error represents the
number
of
times
an
error
occurs.

(2,3.3) Abortion and Completion
of
Test
PC-7000A
PC-7100
Although [[ESCJ J and
[[F2J]
are available while
the
test
is
conducted, a time
lag
occurs because these key opera-
tions
are
processed
in
the state where the executing pro-
gram
step
is
completed.
By
pressing [[ESC] J, control exits
to
the
MEM
test
menu
(Figure
MEM-ll.
By
pressing
[[F2)],
the system displays the following
message on the lower left screen and aborts the test.
"Test stopped by user."
At
the
time,
by
pressing
[[Fl
J
J,
the system continues the
test;
by
pressing [[ESCJ
J,
control exits
to
the
MEM
test
menu (Figure MEM-l).
Whenever one test
is
completed, the system increments the
pass
count and repeats the test.
(2.3.4) Error Processing
When
the total error
is
zero,
the
system does not
detect
an
error
in
the test.
On
the other hand, if the system detects
an
error, it displays the following error message on the
error
message field.
"Memory error! !"
In
addition,
it
the
Error
Stop
is
set
to
"Yes", the system
displays the following message and aborts the test.
"Test stopped !!"
If
the
Error
Stop
is
specified
to
"No". the system displays
only the preceding message and continues the test_
(3) Decision Standard
The system represents a compare error unless the total error
is
"0" when the test
is
completed_
If
the
system detects an
error,
it
displays the address, data, and the relating
Ie
number where the
error
occurs.
All
addr~sses
being displayed
are
physical addresses
of
the
memory.

the following, this test
is
exemplified
