LPDDR3 x16 ProposalLPDDR3 x16 Proposal
Justification of LPDDR3 x16 for Ultra Thin NB• Very low power x16 solution dedicated to Ultra Thin NB & compatible with LPDDR3
Standby Power Cost Performance Granularity Product Lineup
LPDDR3x16
Low standby Power , enough to meet AOAC requirement
Cheaper than LPDDR3 x32 :Smaller Chipsize by x16 org.
Same performance as DDR3L
Higher depth over x32 -> More memory for notebook
Simplify product lineup
