So, remember the lead-time, the cycle-time of wafers in the fab tends to be in the two to three months range and the wafers that you start today by the time they are shipping to the customers that time ends up being, including the time for assembly and test ends up being three to four months later. So, in this environment of really tightness across all end market segments, planning our wafer starts and dedicating them toward various end markets is really critically important. So, this is the kind of activity that our team is always engaged in, in terms of working closely with customers and understanding their demand mix. So, not just total bit demand, but the bit mix of that demand between various product types, because it's extremely important that we start our wafers in line with the expectation of our customers demand few months down the road, given again the cycle-time considerations. So, we are always managing this mix, but again, we would point out that we are seeing supply shortages for us across all end market segments and across all nodes of DRAM as well. And in this environment, we -- this is why, as I mentioned earlier, the lead-time that customers is important and it is an environment where flexibility in terms of, for customers to switch between one product type to another product type is more limited now. When we had more inventory in DRAM before, that was easier to manage, now that the inventory is running at these lean levels, managing our supply mix, keeping it in line with the customer mix, this is an ongoing activity here at Micron and our team has done I think a great job. Our supply chain team, our business units and our sales teams have done a great job working with our customers, understanding the market requirements, and managing our business well. And you see the result in terms of how well we have been able to bring inventory both in DRAM as well as in NAND. And of course, we are continuing to push for SSDs and multi-chip packages toward our higher density solutions as well, because again, all those considerations are important in this environment of tight supply and the tightness in terms of supply-only increasing as we go through the year. So, this is getting a lot of focus Harlan.
