The business case for shrinking an existing memory product to a smaller die or newer process, based on production yield, cost and grade distribution data.
Agreement or business case Work product in the Memory product lifecycle (DRAM, NAND and HBM)
Shrinks are a main way memory makers lower cost during a product's life, but each needs design, mask and qualification investment and customer requalification. The business case weighs the savings against these costs using real production data. Without it, shrinks are started without a clear return, or worthwhile ones are missed.
