A 204-pin PC3-10600 DDR3 SO-DIMM. A SO-DIMM slot on a computer motherboard. A SO-DIMM (pronounced "so dim" / ˈ s oʊ d ɪ m /, also spelled SODIMM) or small outline DIMM, is a smaller alternative to a DIMM, being roughly half the physical size of a regular DIMM. The first SO-DIMMs had 72 pins and were introduced by JEDEC in 1997.
Registered (Buffered) DIMM (R-DIMM or RDIMM) modules insert a buffer between the pins of the command and address buses on the DIMM and the memory chips. A high-capacity DIMM might have numerous memory chips, each of which must receive the memory address, and their combined input capacitance limits the speed at which the memory bus can operate.
Dual-channel memory slots, color-coded orange and yellow for this particular motherboard. Dual-channel-enabled memory controllers in a PC system architecture use two 64-bit data channels. Dual-channel should not be confused with double data rate (DDR), in which data exchange happens twice per DRAM clock. The two technologies are independent of ...
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.
2011: In January, Samsung announced the completion and release for testing of a 2 GB [1] DDR4 DRAM module based on a process between 30 and 39 nm. [28] It has a maximum data transfer rate of 2133 MT/s at 1.2 V, uses pseudo open drain technology (adapted from graphics DDR memory [29]) and draws 40% less power than an equivalent DDR3 module. [28 ...
Memory controller with differential serial connections to DDR2 FB-DIMMs. The AMB is visible in the center of each DIMM. A Fully Buffered DIMM (FB-DIMM) is a type of memory module used in computer systems. It is designed to improve memory performance and capacity by allowing multiple memory modules to be each connected to the memory controller ...
PC2-5300 DDR2 SO-DIMM (for notebooks) Comparison of memory modules for desktop PCs (DIMM) Comparison of memory modules for portable/mobile PCs (SO-DIMM) The key difference between DDR2 and DDR SDRAM is the increase in prefetch length. In DDR SDRAM, the prefetch length is two bits for every bit in a word; whereas it is four bits in DDR2 SDRAM.
In 2002, Cenatek produced the Rocket Drive, max 4 GB, which had four DIMM slots for PC133 memory, with up to a maximum of four gigabytes of storage. At the time, common desktop computers used 64 to 128 megabytes of PC100 or PC133 memory. The one gigabyte PC133 modules (the largest available at the time) cost approximately $1,300 (equivalent to ...
