  2. LPDDR - Wikipedia

    en.wikipedia.org/wiki/LPDDR

    As with LPDDR4, writes must start at a multiple-of-16 address with B0–B3 zero, but reads may request a burst be transferred in a different order by specifying a non-zero value for B3. As with LPDDR4, to read some data requires 4 commands: two activate commands to select a row, then a CAS and a read command to select a column.

  3. NEMA enclosure types - Wikipedia

    4 and 4X: Watertight. Must exclude at least 65 GPM of water from a 1-inch nozzle delivered from a distance not less than 10 feet for 5 min. Used outdoors on ship docks, in dairies, in wastewater treatment plants and breweries. X (as 4X) indicates additional corrosion resistance. 5: Dust-tight.

  4. Tank classification - Wikipedia

    en.wikipedia.org/wiki/Tank_classification

    Tank classification is a taxonomy of identifying either the intended role or weight class of tanks.The classification by role was used primarily during the developmental stage of the national armoured forces, and referred to the doctrinal and force structure utility of the tanks based on design emphasis.

  5. Storage tank - Wikipedia

    en.wikipedia.org/wiki/Storage_tank

    A bulk milk cooling tank is a storage tank located in a dairy farm's milkhouse used for cooling and holding fluid milk at a low temperature until it can be picked up by a milk hauler. Since milk leaves the udder at approximately 35 °C, milk tanks are needed to rapidly cool fresh raw milk to a storage temperature of 4 °C to 6 °C, thereby ...

  6. High Bandwidth Memory - Wikipedia

    en.wikipedia.org/wiki/High_Bandwidth_Memory

    High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.It is used in conjunction with high-performance graphics accelerators, network devices, high-performance datacenter AI ASICs, as on-package cache in CPUs [1] and on-package RAM in upcoming CPUs, and FPGAs and in some supercomputers ...

  7. DDR5 SDRAM - Wikipedia

    en.wikipedia.org/wiki/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. [5]

  8. Memory rank - Wikipedia

    en.wikipedia.org/wiki/Memory_rank

    There is only a little difference between a dual rank UDIMM and two single-rank UDIMMs in the same memory channel, other than that the DRAMs reside on different PCBs. The electrical connections between the memory controller and the DRAMs are almost identical (with the possible exception of which chip selects go to which ranks). Increasing the ...

  9. 3D XPoint - Wikipedia

    en.wikipedia.org/wiki/3D_XPoint

    Optane 900p sequential mixed read-write performance, compared to a wide range of well reputed consumer SSDs. The graph shows how traditional SSD's performance drops sharply to around 500–700 MB/s for all but nearly-pure read and write tasks, whereas the 3D XPoint device is unaffected and consistently produces around 2200–2400 MB/s throughput in the same test.
