Note: 1. RTT1(EFF) and RTT2(EFF) are determined by separately applying VIH(AC) and VIL (AC) to the ball being tested, and then measuring current, I(VIH(AC)), and I(VIL(AC)), respectively.
2. Measure voltage (VM) at tested ball with no load
RTT(EFF) = VIH(AC) - VIL(AC)
I(VIH(AC)) - I(VIL(AC))
VM =
(2 x VM - 1) x 100

Note: These typical thermal resistances are for each DRAM die, if using the total power of the MCP, divide the
given values by 5.
