CAMM (memory Module)
Compression Attached Memory Module (CAMM) is a memory module form factor which uses a land grid array, and developed at Dell by engineer Tom Schnell as a replacement for DIMMs and DIMM#SO-DIMM, SO-DIMMs which use edge connectors and had been in use for about 25 years. The first SO-DIMMs were introduced by JEDEC in 1997. CAMM was created to overcome technical limitations of traditional edge connector, slotted DIMM. The CAMM module allows for shorter traces on the motherboard PCB as compared to SO-DIMM, allowing the memory to be run with less power and at higher speeds. The memory module is pressed and held in place against a bar with land grid array pin contacts which connect to the motherboard. Advantages of CAMM include lower thickness, allows for replaceable LPDDR modules, faster speeds above 6400MT/s, higher capacities up to 128GB per module and higher memory bandwidth. Disadvantages are that it cannot be mounted without tools and uses screws. Systems with CAMM memory already ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory Module
In computing, a memory module or RAM stick is a printed circuit board on which Computer memory, memory integrated circuits are mounted. Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers, workstations, and Server (computing), servers. The first memory modules were proprietary designs that were specific to a model of computer from a specific manufacturer. Later, memory modules were standardized by organizations such as JEDEC and could be used in any system designed to use them. Distinguishing characteristics of computer memory modules include voltage, capacity, speed (i.e., bit rate), and computer form factor, form factor. Overview Types of memory module include: * TransFlash Memory Module * SIMM, a single in-line memory module * DIMM, dual in-line memory module ** Rambus memory modules are a subset of DIMMs, but are normally referred to as RIMMs ** SO-DIMM, small outline DIMM, a smaller version of the ...

DDR5 SDRAM
Double Data Rate 5 Synchronous Dynamic Random-Access Memory (DDR5 SDRAM) is a type of synchronous dynamic random-access memory. Compared to its predecessor DDR4 SDRAM, DDR5 was planned to reduce power consumption, while doubling bandwidth. The standard, originally targeted for 2018, was released on July 14, 2020. A new feature called Decision Feedback Equalization (DFE) enables input/output (I/O) speed scalability for higher bandwidth and performance improvement. DDR5 has about the same latency as DDR4 and DDR3. DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. DDR5 also has higher frequencies than DDR4, up to 9600 MT/s is currently possible, 8200 MT/s translates into around 66 GB/s of bandwidth. Using liquid nitrogen 13000 MT/s speeds were achieved. Rambus announced a working DDR5 dual in-line memory module (DIMM) in September 2017. On November 15, 2018, SK Hynix announced completion of its first DDR5 RAM chip; running at 5.2 GT/s at 1.1 V ...

Computer Memory Form Factor
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computer ...
