Notes: 1. A start-up delay of 200
μ
s is required after power-up, followed by a minimum of eight initialization
cycles (
RAS
-only refresh or
CAS
before
RAS
refresh) before proper device operation is achieved.
2. The AC characteristics assume t
T
= 5ns.
3. V
IH
(Min.) and V
IL
(Max.) are reference levels for measuring input timing signals. Transition times (t
T
)
are measured between V
IH
and V
IL
.
4. -50 is measured with a load circuit equivalent to 2TTL load and 50pF, and -60/-70 is measured with a
load circuit equivalent to 2TTL load and 100pF.
5. Operation within the t
RCD
(Max.) limit ensures that t
RAC
(Max.) can be met.
t
RCD
(Max.) is specified as a reference point only. If t
RCD
is greater than the specified t
RCD
(Max.) limit,
then the access time is controlled by t
CAC
.
6. Operation within the t
RAD
(Max.) limit ensures that t
RAC
(Max.) can be met.
t
RAD
(Max.) is specified as a reference point only. If t
RAD
is greater than the specified t
RAD
(Max.) limit,
then the access time is controlled by t
AA
.
7. t
OFF
(Max.) and t
OEZ
(Max.) define the time at which the output achieved the open circuit condition and
are not referenced to output voltage levels.
8. t
RCH
or t
RRH
must be satisfied for a read cycle.
9. t
WCS
, t
CWD
, t
RWD
, t
AWD
and t
CPWD
are not restrictive operating parameters. They are included in the data
sheet as electrical characteristics only. If t
WCS
≥
t
WCS
(Min.), then the cycle is an early write cycle and
the data out will remain open circuit (high impedance) throughout the entire cycle. If t
CWD
≥
t
CWD
(Min.), t
RWD
≥
t
RWD
(Min.), t
AWD
≥
t
AWD
(Min.) and t
CPWD
≥
t
CPWD
(Min.), then the cycle is a read modify
write cycle and data out will contain data read from the selected cell; if neither of the above sets of
conditions is satisfied, then the condition of the data out (at access time) is indeterminate.
10.These parameters are referenced to the
CAS
, leading edges in an early write cycle, and to the
WE
leading edge in an
OE
control write cycle, or a read modify write cycle.
11. The test mode is initiated by performing a
WE
and
CAS
before
RAS
refresh cycle. This mode is
latched and remains in effect until the exit cycle is generated. In a test CA0, CA1 and CA10 are not
used and each DQ pin now access 8-bit locations. Since all 4 DQ pins are used, a total 32 data bits can
be written in parallel into the memory array. In a read cycle, if 8 data bits are equal, the DQ pin will
indicate a high level. If the 8 data bits are not equal, the DQ pin will indicate a low level. The test mode
is cleared and the memory device returned to its normal operating state by performing a
RAS
-only
refresh cycle or a
CAS
before
RAS
refresh cycle.
12.In a test mode read cycle, the value of access time parameter is delayed for 5ns for the specified value.
These parameters should be specified in test mode cycle by adding the above value to the specified
value in this data sheet.
