  2. DDR SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR_SDRAM

    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 ...

  3. DIMM - Wikipedia

    en.wikipedia.org/wiki/DIMM

    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 ...

    en.wikipedia.org/wiki/Memory_module

    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 DIMM, used in laptops; Compression Attached Memory Module, thinner than SO-DIMM

    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 ...

  6. Serial presence detect - Wikipedia

    en.wikipedia.org/wiki/Serial_presence_detect

    In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.

  7. JEDEC memory standards - Wikipedia

    en.wikipedia.org/wiki/JEDEC_memory_standards

    The standards specify memory module label formats for end-user markets. [11] For example: 1GB 2Rx4 PC2-3200P-333-11-D2 is a 1 GB DDR2 Registered DIMM, with address/command parity function, using 2 ranks of x4 SDRAMs operational to PC2-3200 performance with CAS Latency = 3, tRCD = 3, tRP = 3, using JEDEC SPD revision 1.1, raw card reference ...

  9. Registered memory - Wikipedia

    en.wikipedia.org/wiki/Registered_memory

    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.
