Different types of laptop RAM

RAM contains multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be "8-bit" or "16-bit", etc. devices.

In today's technology, random-access memory takes the form of integrated circuits. RAM is normally associated with volatile types of memory (such as DRAM modules), where stored information is lost if power is removed, although non-volatile RAM has also been developed.^[1]Other types of non-volatile memories exist that allow random access for read operations, but either do not allow write operations or have other kinds of limitations on them. These include most types of ROM and a type of flash memory called NOR-Flash.

With the advancement in technology we have different types of laptop RAM and if you want to know how to select the right RAM you must know the Laptop RAM difference

The different varieties of RAM in our laptops and they can be of DDR1, DDR2 or DDR3 types and they all come under the SDRAM category. When you want to know the Laptop RAM difference, you must understand that though all the three types of RAM do the same function in providing the memory support to your laptop during its operation they have some vital differences both in physical design and performance design.
