  2. DDR5 SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR5_SDRAM

    DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. [8] [3] DDR5 also has higher frequencies than DDR4, up to 8GT/s which translates into 64 GB/s (8 gigatransfers/second × 64-bits/module / 8 bits/byte = 64 GB/s) of bandwidth per DIMM. Rambus announced a working DDR5 dual in-line memory module (DIMM) in September 2017.

  3. DDR SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR_SDRAM

    1 GB PC3200 non-ECC modules are usually made with 16 512 Mbit chips, 8 on each side (512 Mbits × 16 chips) / (8 bits (per byte)) = 1,024 MB. The individual chips making up a 1 GB memory module are usually organized as 2 26 8-bit words, commonly expressed as 64M×8. Memory manufactured in this way is low-density RAM and is usually compatible ...

  4. LPDDR - Wikipedia

    en.wikipedia.org/wiki/LPDDR

    Data lines and control connected in parallel to a 16-bit data bus, and only chip selects connected independently per channel. To two halves of a 32-bit wide data bus, and the control lines in parallel, including chip select. To two independent 16-bit wide data buses; Each die provides 4, 6, 8, 12, or 16 gigabits of memory, half to each channel ...

  5. DIMM - Wikipedia

    The first notch is the DRAM key position, which represents RFU (reserved future use), registered, and unbuffered DIMM types (left, middle and right position, respectively). The second notch is the voltage key position, which represents 5.0 V, 3.3 V, and RFU DIMM types (order is the same as above).

  6. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    (For example, if a computer has 2 GB (1024 3 B) of RAM and a 1 GB page file, the operating system has 3 GB total memory available to it.) When the system runs low on physical memory, it can " swap " portions of RAM to the paging file to make room for new data, as well as to read previously swapped information back into RAM.

  7. Synchronous dynamic random-access memory - Wikipedia

    Thus, a 200 MHz memory core is combined with IOs that each operate eight times faster (1600 megabits per second). If the memory has 16 IOs, the total read bandwidth would be 200 MHz x 8 datawords/access x 16 IOs = 25.6 gigabits per second (Gbit/s) or 3.2 gigabytes per second (GB/s).

  8. Internet in Ethiopia - Wikipedia

    en.wikipedia.org/wiki/Internet_in_Ethiopia

    In Ethiopia, the Internet penetration rate is 25% as of January 2022, and it is currently attempting a broad expansion of access throughout the country. [1] These efforts have been hampered by the largely rural makeup of the Ethiopian population and the government's refusal to permit any privatization of the telecommunications market. [1]

  9. Regions of Ethiopia - Wikipedia

    en.wikipedia.org/wiki/Regions_of_Ethiopia

    Ethiopia is a federation subdivided into ethno-linguistically based regional states (Amharic: plural: ክልሎች kililoch; singular: ክልል kilil; Oromo: singular: Naannoo; plural: Naannolee) and chartered cities (Amharic: plural: አስተዳደር አካባቢዎች astedader akababiwoch; singular: አስተዳደር አካባቢ astedader akabibi).
