Laptop computer memory is a complicated field. Most commonly used are the SODIMM chips/cards. They are divided in to several groups and sizes.
SODIMM have the following sizes:
72pins
100pins
144pins
200pins
204pins
The 72 and 100 pin models only support 32bil data transfer rates, and as such are not in use vary much anymore. It’s important to understand that these modules are not interchangeable and you have to look at your laptops manual to make sure to get a module that is right for your computer.
