Chapter 6. Memory

Laptop systems use the same basic types of memory chips as desktop systems, but not the same types of modules. Instead of the standard SIMMs (single inline memory modules) or DIMMs (dual inline memory modules) that desktop systems use, laptops and other portable systems use different modules with smaller form factors, intended to better fit the more compact design of most portables. This chapter examines the different types of memory chips and modules found in modern laptop and other portable systems, and it discusses how to upgrade memory in these systems as well.
