  2. LPDDR - Wikipedia

    en.wikipedia.org/wiki/LPDDR

    Each die provides 4, 6, 8, 12, or 16 gigabits of memory, half to each channel. Thus, each bank is one sixteenth the device size. This is organized into the appropriate number (16 K to 64 K) of 16384-bit (2048-byte) rows. Extension to 24 and 32 gigabits is planned, but it is not yet decided if this will be done by increasing the number of rows ...

    16,384 bits (2 kibibytes) – one page of typed text, [4] RAM capacity of Nintendo Entertainment System: 2 15: 32,768 bits (4 kibibytes) 2 16: 65,536 bits (8 kibibytes) 10 5: 100,000 bits 2 17: 131,072 bits (16 kibibytes) – RAM capacity of the smallest ZX Spectrum. 2 18: 262,144 bits (32 kibibytes) - RAM capacity of Matra Alice 90

  4. RAM limit - Wikipedia

    en.wikipedia.org/wiki/RAM_limit

    Limits on physical memory for 32-bit platforms also depend on the presence and use of Physical Address Extension (PAE), which allows 32-bit systems to use more than 4 GB of physical memory. PAE and 64-bit systems may be able to address up to the full address space of the x86 processor.

  5. 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.

  6. Megabyte - Wikipedia

    en.wikipedia.org/wiki/Megabyte

    In this convention, one thousand and twenty-four megabytes (1024 MB) is equal to one gigabyte (1 GB), where 1 GB is 1024 3 bytes (i.e., 1 GiB). Mixed 1 MB = 1 024 000 bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk , which actually has a capacity of 1 474 560 bytes .

  7. Page (computer memory) - Wikipedia

    en.wikipedia.org/wiki/Page_(computer_memory)

    Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system. [ 1 ] [ 2 ] [ 3 ] A transfer of pages between main memory and an auxiliary store, such as a hard disk drive , is referred to as paging or swapping.

  8. CompactFlash - Wikipedia

    en.wikipedia.org/wiki/CompactFlash

    Seagate's 8 GB ST68022CF drive [20] spins up fully within a few revolutions but current drawn can reach up to 350 milliamps and runs at 40-50 mA mean current. Its average seek time is 8 ms and can sustain 9 MB/s read and write, and has an interface speed of 33 MB/s. Hitachi's 4 GB Microdrive is 12 ms seek, sustained 6 MB/s.

  9. 2 GB limit - Wikipedia

    en.wikipedia.org/wiki/2_GB_limit

    The 2 GB limit refers to a physical memory barrier for a process running on a 32-bit operating system, which can only use a maximum of 2 GB of memory. [1] The problem mainly affects 32-bit versions of operating systems like Microsoft Windows and Linux, although some variants of the latter can overcome this barrier. [2]
