Are you interested in DIMM (dual in-line memory module)?
If you are, then you are in the right place.
This post from MiniTool has gathered a lot of information about it such as its types.
And it’s possible for you to also know the difference between DIMM vs SIMM.
Introduction to DIMM
What is DIMM?
It is short for dual in-line memory module.
A DIMM is a small circuit board that contains one or several random access memory (RAM) chips.
It connects to the computer motherboard via pins.
DIMMs store each data bit in a separate memory cell.
DIMMs adopt a 64-bit data path because the processors used in personal computers possess a 64-bit data width.
DIMMs are commonly used in desktops, laptops, printers, and other devices.
With the development of fasterdynamic random access memory(DRAM), DIMM circuit boards have also evolved.
Another development of DIMMs is the use of cooling fins or structures directly connected to the DIMM.
They run quicker and cost less, UDIMMs are not as stable as registered memory.
Commands are sent directly from the memory controller residing in the CPU to the memory module.
The AMB bus is divided into a 14-bit read bus and a 10-bit write bus.
With a dedicated read/write bus means that reads and writes can occur simultaneously, which improves performance.
RDIMMs have on-board memory registers located between the memory and the memory controller.
Therefore, the instruction may take about one CPU cycle longer.
Nevertheless, the buffering reduces the burden on the CPUs memory controller.
Thus, the memory controller can only see the iMB, not the DRAM chip.
The memory buffer then handles all read and write operations to the DRAM chip, increasing capacity and speed.
SO-DIMMs are mainly used in portable computing devices such as laptops and tablets.
The difference from standard DIMMs is that DDR4 SO-DIMMs have 260 pins and DRR4 DIMMs have 288 pins.
PCs and servers use standard DIMMs.
VLP DIMMs were developed to meet the space requirements of blade servers.
