Which memory module type is specifically designed for laptops?

The memory module type specifically designed for laptops is SO-DIMM (Small Outline Dual In-line Memory Module). This design is smaller and more compact than standard DIMM modules, making it well-suited for the limited space available within laptops. SO-DIMMs typically have a smaller form factor, which is essential for fitting into the more compact chassis of portable devices without compromising performance and capacity.

In contrast, standard DIMMs are larger and commonly used in desktop computers, which have more physical space for larger components. SDRAM (Synchronous Dynamic Random Access Memory) refers to a type of memory technology applied in various memory modules but does not specify the form factor. RDIMM (Registered DIMM) is used primarily in server and workstation environments for enhanced stability and performance, but it is not designed for laptops.
