Remark IDD: DRAM current, ICC: AMB current
Notes: 1. Based on DDR2 SDRAM component specification.
2. Refer to JESD51-3 “Low effective thermal conductivity Test board for leaded surface mount packages”
under JESD51-2 standard.
3. DT parameter is derived as following: DTx = IDDx × VDD × Psi T-A, where IDDx definition is based on
JEDEC DDR2 SDRAM component specification and at VDD=1.9V, it is the datasheet (worst case) value,
and Psi T-A is the programmed value of Psi T-A (value in SPD Byte 33).
