On SPRS647B, there are two DDR3 channel supported.
two ways to implement 2GB DDR3:
1.four 4Gb(x16) DDR3, each channel will have two 4Gb DDR3
2.eight 2Gb(x8) DDR3, each channel will have four 2Gb DDR3
Which one is suggested by TI?
If we want to down size to 1GBon DDR3, can we only change 4Gb to 2Gb on way1 or change 2Gb to 1Gb on way2, is it right?
