Note: This information is intended to be used as a guide to identifying the memory technology used for SDRAM DIMMs and
may not include all technologies. Some of the configurations may not exist in the marketplace.
For example, a 32-MB DIMM with 8 chips per side for 16 chips total is most likely comprised of
16 Mb (2M×8) technology SDRAMs giving a data width of ×8.
That same 32-MB DIMM with only 4 chips on one side is most likely comprised of 64 Mb (4M×16)
technology SDRAMs with a data width of ×16.
