  2. NEC V20 - Wikipedia

    en.wikipedia.org/wiki/NEC_V20

    The V20 was fabricated in 2-micron CMOS technology. [5] [3] Early versions ran at speeds of 5, 8, and 10 MHz. [6]: 2 In 1990, an upgrade to the fabrication process technology resulted in the V20H and V20HL, with improved performance and reduced power consumption. [5] Later versions added speeds of 12 and 16 MHz.

  3. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    Nonvolatile BIOS memory refers to a small memory on PC motherboards that is used to store BIOS settings. It is traditionally called CMOS RAM because it uses a volatile, low-power complementary metal–oxide–semiconductor (CMOS) SRAM (such as the Motorola MC146818 [1] or similar) powered by a small battery when system and standby power is off. [2]

  4. Southbridge (computing) - Wikipedia

    The CPU is located at the top of the map at due north. The CPU is connected to the chipset via a fast bridge (the northbridge) located north of other system devices as drawn. The northbridge is connected to the rest of the chipset via a slow bridge (the southbridge) located south of other system devices as drawn.

  5. Power-on self-test - Wikipedia

    en.wikipedia.org/wiki/Power-on_self-test

    The first memory location the CPU tries to execute is known as the reset vector. In the case of a hard reboot, the northbridge will direct a code fetch request to the BIOS located on the system flash memory. For a warm boot, the BIOS will be located in the proper place in RAM and the northbridge will direct the reset vector call to the RAM. In ...

    en.wikipedia.org/wiki/BIOS

    In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -⁠ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

  7. EPROM - Wikipedia

    Later the decreased cost of the CMOS technology allowed the same devices to be fabricated using it, adding the letter "C" to the device numbers (27xx(x) are n-MOS and 27Cxx(x) are CMOS). While parts of the same size from different manufacturers are compatible in read mode, different manufacturers added different and sometimes multiple ...

    The "It's now safe to power off the system" screen in Windows 10 and 11. Microsoft's Windows 98 was the first operating system to implement ACPI, [ 17 ] [ 18 ] but its implementation was somewhat buggy or incomplete, [ 19 ] [ 20 ] although some of the problems associated with it were caused by the first-generation ACPI hardware. [ 21 ]

    The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
