What is DIMM in the Computer Network?
DIMM represents the "Dual In-Line Memory Module" and is a limited circuit board that manages memory chips. It needs a 64-bit bus to the memory, whereas a single in-line memory module (SIMM) only has a 32-bit path. This allows DIMMs to transfer more information at once.
DIMM includes a sequence of memory known as dynamic random access memory (DRAM), which supports primary storage, the main memory that always reads and executes saved instructions or information directly to the CPU.
DIMM is an attempt to enhance the previous single inline memory module (SIMM), which facilitates matched pairs. DIMM operates only one circuit board, thus improving memory speed and storage. DIMM also has a much smaller circuit board and clear insertion distinguished from SIMM.
There are various types of DIMM which are as follows −
Registered DIMM (RDIMM)
This type of DIMM is also known as buffered DIMM. Registered DIMM is generally used in those servers and applications which require establishment and durability.
It is the best choice for our servers in most cases. The register memory module has a register that is presented between the DRAM modules and the memory controller of the system. As the additional circuit is needed, so it is costlier. Because of the use of buffers, the clock cycle is improved.
Unbuffered DIMM (UDIMM)
This type of DIMM is also called Unregistered Memory. It is generally used on laptops and desktops. Unbuffered DIMMs run faster, and the cost of them is low. Unlike the registered DIMM, it is not stable. In this type of DIMM, instructions are sent directly to the memory module from the memory controller.
Fully-buffered DIMM (FB-DIMM)
In the systems, FB-DIMM is used as primary memory, which requires large volumes, such as servers and workstations. The architecture of FB-DIMM specifies the 'Advance Memory Buffer' (AMB), which is presented between the memory module and the controller of memory.
Load-Reduced DIMM (LR-DIMM)
LR-DIMM stands for load-reduced dual inline memory module. LRDIMM memory chips are used in a server environment, such as data centres and cloud computing, and in highperformance computers.
Small-Outline Dual Memory Module (S0-DIMM)
SODIMM stands for Small-Outline Dual Inline Memory Module. It is a small computer expansion card used for RAM. It is a smaller version of the DIMM and is commonly used in laptops, all-in-ones, and other small form factor PCs.
