Density & Rank

Module Density	Module Configuration	Chip Configuration	Chip Density	Number of Chips	Rank	Notes
Module density is always writen with capital “B” and pronounced as Bytes 1 Bytes = 8 bits	Refer x72 below means ECC (main products’ feature that we offer), x64 is non ECC (more commodity products)	Number of cells in a chip. Shown below is (Depth x Width) of Chip for x8 chips. There are also x4 and x16 chips available for special application	Chip density is always writen with small “b” and pronouced as bits	Numbers of chips that assembled on the PCB to make the Module Density	Set of chips
