26.

ODT turn-off time tAOF (MIN) is when the device starts to turn off

ODT resistance. ODT turn off time tAOF (MAX) is when the bus is in

high impedance. Both are measured from tAOFD.

27.

This parameter has a two clock minimum requirement at any tCK.

28.

tDELAY is calculated from tIS + tCK + tIH so that CKE registration

LOW is guaranteed prior to CK, CK# being removed in a system

RESET condition.

29.

tISXR is equal to tIS and is used for CKE setup time during self

refresh exit.

30.

No more than 4 bank ACTIVE commands may be issued in

a given tFAW (MIN) period. tRRRD (MIN) restriction still applies.

The tFAW (MIN) parameter applies to all 8 bank DDR2 devices,

regardless of the number of banks already open or closed.

31.

tRPA timing applies when the PRECHARGE(ALL) command is

issued, regardless of the number of banks already open or closed.

If a single-bank PRECHARGE command is issued, tRP timing

applies. tRPA (MIN) applies to all 8-bank DDR2 devices.

32.

Value is minimum pulse width, not the number of clock

registrations.

33.

Applicable to Read cycles only. Write cycles generally require

additional time due to Write recovery time (tWR) during arto

precharge.

34.

tCKE (MIN) of 3 clocks means CKE must be registered on three

consecutive positive clock edges. CKE must remain at the valid

input level the entire time it takes to achieve the 3 clocks of

registration. Thus, after any CKE transition, CKE may not transition

from its valid level during the time period of tIS + 2* tCK + tIH.

35.

This parameter is not referenced to a speciﬁc voltage level, but

speciﬁed when the device output is no longer driving (tRPST) or

beginning to drive (tRPRE).

36.

When DQS is used single-ended, the minimum limit is reduced by

100ps.
