Self-Refresh Current
I_DD6
CKE ≤ 0.2 V; external clock off, CK and CK at 0 V; Other control and address inputs are FLOATING, Data
bus inputs are FLOATING. I_DD6 current values are guaranteed up to T_CASE of 85 °C max.
All Bank Interleave Read Current
I_DD7
6)
All banks are being interleaved at minimum t_RC without violating t_RRD using a burst length of 4. Control
and address bus inputs are STABLE during DESELECTS. I_out = 0 mA.
1) V_DDQ = 1.8 V ± 0.1 V; V_DD = 1.8 V ± 0.1 V
2) I_DD specifications are tested after the device is properly initialized and I_DD parameter are specified with ODT disabled.
3) Definitions for I_DD see Table 20
4) For two rank modules: for all active current measurements the other rank is in Precharge Power-Down Mode I_DD2P
5) For details and notes see the relevant Qimonda component data sheet
6) I_DD1, I_DD4R and I_DD7 current measurements are defined with the outputs disabled (I_OUT = 0 mA). To achieve this on module level the output
buffers can be disabled using an EMRS(1) (Extended Mode Register Command) by setting A12 bit to HIGH.

Description
TABLE 20
Definitions for I_DD
V_IN ≤ V_IL(ac).MAX, HIGH is defined as V_IN ≥ V_IH(ac).MIN
Inputs are stable at a HIGH or LOW level
Inputs are V_REF = V_DDQ /2
Inputs are changing between HIGH and LOW every other clock (once per 2 cycles) for address and control
signals, and inputs changing between HIGH and LOW every other data transfer (once per cycle) for DQ
signals not including mask or strobes
