a. All parameters assume proper device initialization.

b. Tests for AC timing may be considered at norminal supply voltage levels, but the related specification and device operation are guaranteed for the full

voltage and temperature range specified.

c. CK and CK# single-ended input slew rate must be greater than or equal to 3V/ns. The slew rate is measured between VREFC crossing and VIXCK(AC)

d. Parameter fCKBG4 is required for those devices supporting both 3*tCK and 4*tCK setting for bank groups. Devices supporting only 3*tCK or 4*tCK

need only to specify fCKBG.

e. Parameter fCKPIN applies when the alignment point in MR6, bit A0 is set to “at pins”, the phase difference between the WCK and CK clocks at the

DRAM pins is within tWCK2CKSYNC or tWCK2CK for pin mode and no phase search in WCK2CK training is performed.

f. Parameter fCKRDQS applies when RDQS mode is enabled in AR3, bit A5.

g. Parameter fCKBREFD2 applies when the data input reference voltage in MR7, bit A7 (Half VREFD) is set to VREFD2.

h. Parameter fCKAUTOSYNC applies when WCK2CK Auto Synchronization is enabled in MR7, bit A4.

i. Parameter fCKLF applies when Low Frequency Mode is enabled in MR7, bit A3.

j. By definition the norminal WCK clock cycle time always is 1/2 of the CK clock cycle time (not including jitter).

k. WCK and WCK# single-ended input slew rate must be greater than or equal to 3V/ns. The slew rate is measured between VREFD crossing and

VIXWCK(AC).
