power down entry and exit and for self-refresh entry. Input
buffers excluding CKE are disabled during self-refresh.
CKE is used asynchronously to detect self-refresh exit
condition. Self-refresh termination itself is synchronous.
After
V
REF
has become stable during power-on and
initialisation sequence, it must be maintained for proper
operation of the CKE receiver. For proper self-refresh entry
and exit,
V
REF
must be maintained to this input. CKE must
be maintained HIGH throughout read and write accesses.
Input buffers, excluding CK, CK, ODT and CKE are disabled
during power-down

Pin Configuration and Block Diagrams
The pin configuration of a DDR2 SDRAM is listed by function in
Table 4
. The abbreviations used in the Pin#/Buffer
Type columns are explained in
Table 5
and
Table 6
respectively. The pin numbering for the FBGA package is
depicted in Figure 1 for

Clock Signal CK, Complementary Clock Signal CK
Note:CK and CK are differential system clock inputs. All address
and control inputs are sampled on the crossing of the
positive edge of CK and negative edge of CK. Output (read)
data is referenced to the crossing of CK and CK (both
direction of crossing)
Clock Enable
Note:CKE HIGH activates and CKE LOW deactivates internal
clock signals and device input buffers and output drivers.
Taking CKE LOW provides Precharge Power-Down and
Self-Refresh operation (all banks idle), or Active Power-
Down (row Active in any bank). CKE is synchronous for
