  2. Synchronous dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Synchronous_dynamic_random...

    PC100 is a standard for internal removable computer random-access memory, defined by the JEDEC. PC100 refers to Synchronous DRAM operating at a clock frequency of 100 MHz, on a 64-bit-wide bus, at a voltage of 3.3 V. PC100 is available in 168-pin DIMM and 144-pin SO-DIMM form factors. PC100 is backward compatible with PC66 and was superseded by ...

  3. Memory module - Wikipedia

    en.wikipedia.org/wiki/Memory_module

    In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. [1] Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers, workstations, and servers. The first memory modules were proprietary designs that were specific ...

  4. DIMM - Wikipedia

    Assorted SO-DIMM Modules A 200-pin PC2-5300 DDR2 SO-DIMM. A 204-pin PC3-10600 DDR3 SO-DIMM. A SO-DIMM slot on a computer motherboard. A SO-DIMM (pronounced "so-dimm" / 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 SODIMMs had ...

  5. Memory timings - Wikipedia

    en.wikipedia.org/wiki/Memory_timings

    Memory timings. Memory timings or RAM timings describe the timing information of a memory module or the onboard LPDDRx. Due to the inherent qualities of VLSI and microelectronics, memory chips require time to fully execute commands. Executing commands too quickly will result in data corruption and results in system instability.

  6. Fully Buffered DIMM - Wikipedia

    en.wikipedia.org/wiki/Fully_Buffered_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 using a serial interface, rather than a parallel one. Unlike the parallel bus architecture of traditional DRAMs, an FB ...

  7. Dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Dynamic_random-access_memory

    Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...

  8. Registered memory - Wikipedia

    en.wikipedia.org/wiki/Registered_memory

    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. Registered memory allows a computer system to remain stable with more memory modules than it ...

  9. DDR SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR_SDRAM

    DDR SDRAM. Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits used in computers. DDR SDRAM, also retroactively called DDR1 SDRAM, has been superseded by DDR2 SDRAM, DDR3 SDRAM, DDR4 SDRAM and DDR5 SDRAM.
