A DIMM (Dual In-Line Memory Module) is a popular type of memory module used in computers. It is a printed circuit board with one or both sides (front and back) holding DRAM chips and pins . [ 1 ] The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards , although there are proprietary DIMMs.
To increase memory capacity and bandwidth, chips are combined on a module. For instance, the 64-bit data bus for DIMM requires eight 8-bit chips, addressed in parallel. Multiple chips with common address lines are called a memory rank. The term was introduced to avoid confusion with chip internal rows and banks. A memory module may bear more ...
SDRAM memory module, zoomed. As an example, a 512 MB SDRAM DIMM (which contains 512 MB), might be made of eight or nine SDRAM chips, each containing 512 Mbit of storage, and each one contributing 8 bits to the DIMM's 64- or 72-bit width. A typical 512 Mbit SDRAM chip internally contains four independent 16 MB memory banks. Each bank is an array ...
Two types of DIMMs (dual in-line memory modules): a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom). Memory modules of SK Hynix. In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted.
A module composed of Micron Technology MT47H128M16 chips with the organization 128 Mib × 16, meaning 128 Mi memory depth and 16-bit-wide data bus per chip; if the module has 8 of these chips on each side of the board, there would be a total of 16 chips × 16-bit-wide data = 256 total bits width of data. For a 64-bit-wide memory data interface ...

One 64 GiB DDR5-4800 ECC 1.1 V registered DIMM (RDIMM) Example of an unregistered DIMM (UDIMM) Registered memory (also called buffered memory) is computer memory that has a register between the DRAM modules and the system's memory controller. A registered memory module places less electrical load on a memory controller than an unregistered one.
It was packaged as a 184-pin RIMM (Rambus in-line memory module) form factor, similar to a DIMM (dual in-line memory module). Data is transferred on both the rising and falling edges of the clock signal, a technique known as DDR. To emphasize the advantages of the DDR technique, this type of RAM was marketed at speeds twice the actual clock ...
