We mainly support DDR3, DDR4 for customers who also doing SSD business, to brand customers or computer factories, we also has LPDDR which now only support China Inland major mobile phone and IPAD customers and some smart watch customers. With its high performance and lower consumption, its good for small size smart devices.
