The type of memory module is typically used in laptop computers is known as SODIMM. This stands for small outline dual in-line memory module.
DIMM stands for dual inline memory module
The EDO RAM desktop memory modules have 72 pins and operate at 5V as standard
It is a specific type of computer memory (RAM - Random Access Memory) that is required in all desktop and laptop computers. Kingston is a major company that sells computer memory and 1GB is usually a stick of "ram".
DDR, DDR2, SDR, DDR3, DDR4. SO-dimm are for laptops
A Single Inline Memory Module (SIMM) is a type of memory module that holds RAM chips and connects to a computer's motherboard. It features contacts on one side of the module, allowing for data transfer between the RAM and the system. SIMMs were widely used in older computer systems, offering a compact design that helped to increase memory capacity. However, they have largely been replaced by more advanced memory technologies, such as DIMMs (Dual Inline Memory Modules).
Memory modules are used for adding RAM to a computer motherboard. As a standard computer industry practice the motherboard manufacturers do not add RAM to motherboards but provide slots (empty sockets) to which memory modules can be added as per computer configuration needs of the end user. Semiconductor RAM which is manufactured as standard chips is assembled on printed circuit boards as memory modules of different capacities (e.g 512MB , 1GB or 2GB). Examples include SIMM, DIMM, SODIMM. These module printed circuit board size, shape and signals are standard as defined for various memory types e.g. 200pin laptop DDR2 SODIMM is a common laptop memory type these days. Since there are standard modules for all type of computers, for a specific computer type you can just buy memory module and add RAM to the computer.
A SO-DIMM (Small Outline Dual In-Line Memory Module) typically has either 72 pins or 200 pins, depending on the type of memory it supports. The 72-pin SO-DIMM is used for older SDRAM, while the 200-pin variant is used for DDR, DDR2, DDR3, and DDR4 memory types. The pin count is crucial for compatibility with specific motherboards and devices.
Rambus. Rambus memory is serial and requires that all memory slots be populated. If a memory slot is not populated with a memory module, a continuity module must be used to complete the serial circuit.
