What would a higher number of DRAMs in the specs for a memory chip indicate (e.g. x8 vs. x16)? - dram chip

x8 chips mean high-density low-density x16 means. older computers rather low density chips such as memory interface address lines had less, so that it can not handle high-density chips have.
For example, modules of the old Dell Inspiron notebook chip at low density (256 MB with 16 chips with low density, 256 chips, with 8 high density can not be processed required).
