Field-programmable Gate Array - Basic Process Technology Types

Basic Process Technology Types

  • SRAM - based on static memory technology. In-system programmable and re-programmable. Requires external boot devices. CMOS. Currently in use.
  • Antifuse - One-time programmable. CMOS.
  • PROM - Programmable Read-Only Memory technology. One-time programmable because of plastic packaging. Obsolete.
  • EPROM - Erasable Programmable Read-Only Memory technology. One-time programmable but with window, can be erased with ultraviolet (UV) light. CMOS. Obsolete.
  • EEPROM - Electrically Erasable Programmable Read-Only Memory technology. Can be erased, even in plastic packages. Some but not all EEPROM devices can be in-system programmed. CMOS.
  • Flash - Flash-erase EPROM technology. Can be erased, even in plastic packages. Some but not all flash devices can be in-system programmed. Usually, a flash cell is smaller than an equivalent EEPROM cell and is therefore less expensive to manufacture. CMOS.
  • Fuse - One-time programmable. Bipolar. Obsolete.

Famous quotes containing the words basic, process, technology and/or types:

    “A kiss can be a comma, a question mark or an exclamation point. That’s basic spelling that every woman ought to know.”
    —Mistinguett (1874–1956)

    “The process of discovery is very simple. An unwearied and systematic application of known laws to nature causes the unknown to reveal themselves.”
    —Henry David Thoreau (1817–1862)

    “Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
    —Jackie Torrence (b. 1944)

    “He types his laboured column—weary drudge!
    Senile fudge and solemn:
    Spare, editor, to condemn
    These dry leaves of his autumn.”
    —Robertson Davies (b. 1913)
