Parameter/Condition
Idle current, single or last FBDIMM: L0 state, idle (0 BW); primary channel
enabled, secondary channel disabled, CKE HIGH; command and address lines
stable, DDR2 SDRAM clock active.
Idle current, first FBDIMM: L0 state, idle (0 BW); primary and secondary
channels enabled, CKE HIGH; command and address lines stable, DDR2 SDRAM
clock active.
Idle current, DDR2 SDRAM power-down: L0 state, idle (0 BW); primary and
secondary channels enabled, CKE HIGH; command and address lines floated, DDR2
SDRAM clock active; ODT and CKE driven LOW.
Active Power: L0 state; 50% DDR2 SDRAM BW, 67% READ, 33% WRITE; primary
and secondary channels enabled, CKE HIGH; DDR2 SDRAM clock active.
Active Power, data pass-through: L0 state; 50% DDR2 SDRAM BW to
downstream FBDIMM, 67% READ, 33% WRITE; primary and secondary channels
enabled; command and address lines stable, CKE HIGH; DDR2 SDRAM clock active.
Channel standby: Average power over 42 frames where the channel enters and
exits L0s; DDR2 SDRAM devices Idle (0 BW); CKE LOW; command and address lines
floated; DDR2 SDRAM lock active, ODE and CKE driven LOW.
Training: Primary and secondary channels enabled; 100% toggle on all channel
lanes; DDR2 SDRAM devices idle (0 BW); CKE HIGH, command and address lines
stable; DDR2 SDRAM clock active.

Specifications and Conditions – 4GB
• primary channel drive strength at 100 percent with de-emphasis at –6.5dB, secondary
• Address and data fields are pseudo-random, which provides a 50 percent toggle rate
• Assuming 1 ACTIVATE command and 1 READ/WRITE command per BL = 4 transfer,
• Ten southbound lanes and 14 northbound lanes are enabled and active.
SPD-specific assumptions:
• Number of devices on the specific FBDIMM assumed
• Termination of command, address, and control is actual value used on the FBDIMM
• ECC as per the specific FBDIMM
• SPD specifies ΔT
AMB power-specification assumptions:
• Specific ECC FBDIMM assumed (72-bit data, 14 lanes northbound with DDR2
• Modeled with 27Ω termination for command, address, and clocks, and 47Ω termina-
• AMB specification specifies current for each rail
channel drive strength at 60 percent with de-emphasis at –3dB when enabled.
