7. Measured from the point when DQS/DQS# begins driving the signal, to the point when
DQS/DQS# begins driving the first rising strobe edge.
8. Measured from the last falling strobe edge of DQS/DQS# to the point when DQS/DQS#
finishes driving the signal.
9. CKE input setup time is measured from CKE reaching a HIGH/LOW voltage level to
CK/CK# crossing.
10. CKE input hold time is measured from CK/CK# crossing to CKE reaching a HIGH/LOW
voltage level.
11. Input setup/hold time for signal (CA[9:0], CS#).
12. To ensure device operation before the device is configured, a number of AC boot timing
parameters are defined in this table. The letter b is appended to the boot parameter
symbols (for example, t CK during boot is t CKb).
13. Mobile LPDDR2 devices set some mode register default values upon receiving a RESET
(MRW) command, as specified in Mode Register Definition.
14. The output skew parameters are measured with default output impedance settings
using the reference load.
15. The minimum t CK column applies only when t CK is greater than 6ns.
16. Timing derating applies for operation at 85?C to 105?C when the requirement to derate
is indicated by mode register 4 op-code (see the MR4 Device Temperature (MA[7:0] =
04h) table).
17. DRAM devices should be evenly addressed when being accessed. Disproportionate ac-
cesses to a particular row address may result in reduction of the product lifetime.
