GENERAL DESCRIPTION (cont.)
cycle is always initiated with a row address strobe-in by RAS\
followed by a column address strobed-in by CAS\. CAS\ may
be toggled-in by holding RAS\ LOW and strobing-in different column addresses, thus executing faster memory cycles.
Returning RAS\ HIGH terminates the FAST PAGE MODE
operation.
Returning RAS\ and CAS\ HIGH terminates a memory cycle
and decreases chip current to a reduced standby level. Also,
the chip is preconditioned for the next cycle during the RAS\
HIGH time. Memory cell data is retained in its corrected stated
by maintaining power and executing any RAS\ cycle (READ,
WRITE, RAS\-ONLY, CAS\-BEFORE-RAS\, or HIDDEN
REFRESH) so that all 1,024 combinations of RAS\ addresses
(A0-A9) are executed at least every 16ms, regardless of sequence. The CBR REFRESH cycle will invoke the internal
refresh counter for automatic RAS\ addressing.

NOTES:
point only; if tRAD is greater than the specified tRAD (MAX)
limit, then access time is controlled exclusively by tAA.
19. Either tRCH or tRRH must be satisfied for a READ cycle.
20. tOFF (MAX) defines the time at which the output achieves the
open circuit conditions and is not referenced to VOH or VOL.
21. tWCS, tRWD, tAWD, and tCWD are not restrictive operating parameters. tWCS applies to EARLY-WRITE cycles. tRWD, tAWD,
and tCWD apply to READ-MODIFY-WRITE cycles.
If tWCS
> tWCS (MIN), the cycle is an EARLY-WRITE cycles and the
data output will remain an open circuit throughout the entire
cycle. If tRWD > tRWD (MIN), tAWD > tAWD (MIN) and tCWD >
tCWD (MIN), the cycle is a READ-MODIFY-WRITE and the
data output will contain data read from the selected cell. If
neither of the above conditions is met, the state of the data out
is indeterminate. OE\ held HIGH and WE\ taken LOW after
CAS\ goes LOW results in a LATE-WRITE (OE\ controlled)
cycle. tWCS, tRWD, tCWD, and tAWD are not
applicable in a
LATE-WRITE cycle.
22. These parameters are referenced to CAS\ leading edge
in EARLY-WRITE cycle and WE\ leading edge in LATEWRITE cycles and WE\ leading edge in LATE-WRITE or
READ-MODIFY-WRITE cycle.
23. If OE\ is tied permanently LOW, LATE-WRITE or
READ-MODIFY-WRITE operations are not possible.
24. A HIDDEN REFRESH may also be performed after a
WRITE cycle. In this case, WE\=LOW and OE\=HIGH.
25. tWTS and tWTH are setup and hold specifications for the WE\
pin being held LOW to enable the JEDEC test mode (with CBR
timing constraints). These two parameters are the
inverts
of tWRP and tWRH in the CBR REFRESH cycle.
26. LATE-WRITE and READ-MODIFY-WRITE cycles must
have both tOD and tOEH met (OE\ HIGH during WRITE cycle)
in order to ensure that the output buffers will be open during
the WRITE cycle. The DQs will provide the previously read
data if CAS\ remains LOW and OE\ is taken back LOW after
tOEH is met. If CAS\ goes HIGH prior to OE\ going back LOW,
the DQs will remain open.
27. The DQs open during READ cycles once tOD or tOFF occur. If CAS\ goes HIGH first, OE\ becomes a “don’t care.”
If OE\ goes HIGH and CAS\ stays LOW, OE\ is not a “don’t
care;” and the DQs will provide the previously read data if OE\
is taken back LOW (while CAS\ remains LOW).
28. JEDEC test mode only.
1. All voltages referenced to Vss.
2. This parameter is sampled, not 100% tested. Capacitance is
measured with Vcc=5V, f=1 MHz at less than 50mVrms, TA =
25°C ±3°C, Vbias = 2.4V applied to each input and output
individually with remaining inputs and outputs open.
3. Icc is dependent on cycle rates.
4. Icc is dependent on output loading and cycle rates.
Specified values are obtained with minimum cycle time and the
output open.
5. Enables on-chip refresh and address counters.
6. The minimum specifications are used only to indicate cycle
time at which proper operation over the full temperature range
(-55°C < TA < 125°C) is assured.
7. An initial pause of 100μs is required after power-up
followed by eight RAS\ refresh cycles (RAS\-ONLY or CBR with
WE\ HIGH) before proper device operation is assured. The
eight RAS\ cycle wake-up should be repeated any time the
16ms refresh requirement is exceeded.
8. AC characteristics assume tT = 5ns.
9. VIH (MIN) and VIL (MAX) are reference levels for
measuring timing of input signals. Transition times are
measured between VIH and VIL (or between VIL and VIH).
10. In addition to meeting the transition rate specification, all
input signals must transit between VIH and VIL (or between VIL
and VIH) in a monotonic manner.
11. If CAS\ = VIH, data outputs (DQs) are High-Z.
12. If CAS\ = VIL, data outputs (DQs) may contain data from
the last valid READ cycle.
13. Measured with a load equivalent to two TTL gates and
100pF.
14. Assumes that tRCD < tRCD (MAX). If tRCD is greater than the
maximum recommended value shown in this table, tRAC will
increase by the amount that tRCD exceeds the value shown.
15. Assumes that tRCD > tRCD (MAX)
16. If CAS\ is LOW at the falling edge of RAS\, DQs will be
maintained from the previous cycle. To initiate a new cycle
and clear the data out buffer, CAS\ must be pulsed HIGH for
tCPN.
17. Operation within the tRCD (MAX) limit ensures that tRAC
(MAX) can be met. tRCD (MAX) is specified as a reference
point only; if tRCD is greater than the specified tRCD (MAX) limit,
then access time is controlled exclusively by tCAC.
18. Operation within the tRAD (MAX) limit ensures that tRCD
(MAX) can be met. tRAD (MAX) is specified as a reference

POWER-UP
4 MEG POWER-UP AND REFRESH
CONSTRAINTS
The EIA/JEDEC 4 Meg DRAM introduces two potential
incompatibilities compared to the previous generation 1 Meg
DRAM. The incompatibilities involve refresh and power-up.
Understanding these incompatibilities and providing for them
will offer the designer and system user greater compatibility
between the 1 Meg and 4 Meg.
REFRESH
The most commonly used refresh mode of the 1 Meg is the
CBR (CAS\-BEFORE-RAS\) REFRESH cycle. The CBR for
the 1 Meg specifies the WE\ pin as a “don’t care.” The 4 Meg,
on the other hand, specifies the CBR REFRESH mode with the
WE\ pin held at a voltage HIGH level.
A CBR cycle with WE\ LOW will put the 4 Meg into the
JEDEC specified test mode (WCBR).
The 4 Meg JEDEC test mode constraint may introduce
another problem. The 1 Meg POWER-UP cycle requires a
100μs delay followed by any eight RAS\ cycles. The 4 Meg
POWER-UP is more restrictive in that eight RAS\-ONLY
or CBR REFRESH (WE\ held HIGH) cycles must be used.
The restriction is needed since the 4 Meg may power-up in
the JEDEC specified test mode and must exit out of the test
mode. The only way to exit the 4 Meg JEDEC test mode is
with either a RAS\-ONLY or a CBR REFRESH cycle (WE\
held HIGH).
SUMMARY
1. The 1 Meg CBR REFRESH allows the WE\ pin to be “don’t
care” while the 4 Meg CBR requires WE\ to be HIGH.
2. The eight RAS\ wake-up cycles on the 1 Meg may be any
valid RAS\ cycle while the 4 Meg may only use RAS\-ONLY
or CBR REFRESH cycles (WE\ held HIGH).
