1. The module IDD values are calculated from the component IDD datasheet values as:
n * IDDx[component]
for single bank modules (n: number of components per module bank)
n * IDDx[component] + n * IDD3N[component]
for two bank modules (n: number of components per module bank)
2. The module IDD values are calculated from the component IDD datasheet values as:
n * IDDx[component]
2 * n * IDDx[component]
for single bank modules (n: number of components per module bank)
for two bank modules (n: number of components per module bank)
3. DQ I/O (IDDQ) currents are not included into calculations: module IDD values will be measured differently depending on load conditions
4. Test condition for maximum values: VDD = 2.7V ,Ta = 10°C
