1. Electrical Conditions
• All voltages are referenced to VSS (GND)
• Execute power-up and Initialization sequence before proper device operation is achieved.
• Operation or timing that is not specified is illegal, and after such an event, in order to guarantee proper
operation, the DDR2 Mobile RAM Device must be powered down and then restarted through the
specialized initialization sequence before normal operation can continue.

Notes: 1.
Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect reliability.
2.
See Power-Ramp section “Power-up, initialization and Power-Off” in the individual DDR2 Mobile RAM data sheet for
relationship between power supplies.
3.
VREF ≤ 0.6 x VDDQ; however, VREF may be ≥ VDDQ provided that VREF ≤ 300mV.
4.
Storage Temperature is the case surface temperature on the center/top side of the DDR2 Mobile RAM Device. For the
measurement conditions, please refer to JESD51-2 standard.
Caution
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification. Exposure to Absolute Maximum
Rating conditions for extended periods may affect device reliability.

Notes: 1.
Input set-up/hold time for signal(CA0 – CA9, /CS).
2.
CKE input setup time is measured from CKE reaching high/low voltage level to CK, /CK crossing.
3.
CKE input hold time is measured from CK, /CK crossing to CKE reaching high/low voltage level.
4.
Frequency values are for reference only. Clock cycle time (tCK) shall be used to determine device capabilities.
5.
To guarantee device operation before the DDR2 Mobile RAM Device is configured a number of AC boot timing parameters are defined in the Table 6 on page 13. Boot parameter symbols have the letter b appended, e.g. tCK during boot is
tCKb.
6.
Frequency values are for reference only. Clock cycle time (tCK or tCKb) shall be used to determine device capabilities.
7.
The DDR2 Mobile RAM will set some Mode register default values upon receiving a RESET (MRW) command as specified in “Mode Register Definition” in the individual DDR2 Mobile RAM data sheet.
8.
The output skew parameters are measured with Ron default settings into the reference load.
9.
These parameters should be satisfied with both specification, analog (ns) value and min. tCK.
10.
All AC timings assume an input slew rate of 1V/ns.
11.
Read, Write, and Input Setup and Hold values are referenced to VREF.
12. For low-to-high and high-to-low transitions the timing reference will be at the point when the signal crosses VTT. tHZ
and tLZ transitions occur in the same access time (with respect to clock) as valid data transitions. These parameters
are not referenced to a specific voltage level but to the time when the device output is no longer driving (for tRPST,
tHZ(DQS) and tHZ(DQ) ), or begins driving (for tRPRE, tLZ(DQS), tLZ(DQ) ). Figure 1 shows a method to calculate the
point when device is no longer driving tHZ(DQS) and tHZ(DQ), or begins driving tLZ(DQS), tLZ(DQ) by measuring the
signal at two different voltages. The actual voltage measurement points are not critical as long as the calculation is consistent.

The parameters tLZ(DQS), tLZ(DQ), tHZ(DQS), and tHZ(DQ) are defined as single-ended. The
timing parameters tRPRE and tRPST are determined from the differential signal DQS-/DQS.

Measured from the start driving of DQS – /DQS to the start driving the first rising strobe edge.

15. tDQSCKDS is the absolute value of the difference between any two tDQSCK measurements (within a byte lane) within
a contiguous sequence of bursts within a 160ns rolling window. tDQSCKDS is not tested and is guaranteed by design.
Temperature drift in the system is < 10°C/s. Values do not include clock
jitter.
16.
tDQSCKDM is the absolute value of the difference between any two tDQSCK measurements (within a byte lane) within
a 1.6µs rolling window. tDQSCKDM is not tested and is guaranteed by design. Temperature drift in the system is <
10°C/s. Values do not include clock jitter.
17.
tDQSCKDL is the absolute value of the difference between any two tDQSCK measurements (within a byte lane) within
a 32ms rolling window. tDQSCKDL is not tested and is guaranteed by design. Temperature drift in the system is <
10°C/s. Values do not include clock jitter.

These ‘Timing Reference Loads’ are not intended as a precise representation of any particular system
environment or a depiction of the actual load presented by a production tester. System designers should
use IBIS or other simulation tools to correlate the timing reference load to a system environment.
Manufacturers correlate to their production test conditions, generally one or more coaxial transmission

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR MOS DEVICES
Exposing the MOS devices to a strong electric field can cause destruction of the gate
oxide and ultimately degrade the MOS devices operation. Steps must be taken to stop
generation of static electricity as much as possible, and quickly dissipate it, when once
it has occurred. Environmental control must be adequate. When it is dry, humidifier
should be used. It is recommended to avoid using insulators that easily build static
electricity. MOS devices must be stored and transported in an anti-static container,
static shielding bag or conductive material. All test and measurement tools including
work bench and floor should be grounded. The operator should be grounded using
wrist strap. MOS devices must not be touched with bare hands. Similar precautions
need to be taken for PW boards with semiconductor MOS devices on it.
2
HANDLING OF UNUSED INPUT PINS FOR CMOS DEVICES
No connection for CMOS devices input pins can be a cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input level may be
generated due to noise, etc., hence causing malfunction. CMOS devices behave
differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed
high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected
to VDD or GND with a resistor, if it is considered to have a possibility of being an output
pin. The unused pins must be handled in accordance with the related specifications.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Power-on does not necessarily define initial status of MOS devices. Production process
of MOS does not define the initial operation status of the device. Immediately after the
power source is turned ON, the MOS devices with reset function have not yet been
initialized. Hence, power-on does not guarantee output pin levels, I/O settings or
contents of registers. MOS devices are not initialized until the reset signal is received.
Reset operation must be executed immediately after power-on for MOS devices having
reset function.
