fusible link

fusible link (fuse link) A physical link providing electric continuity across an individual cell in the memory array of a PROM. With this link intact the cell,when interrogated, will display a known logic state. During programming this link can be destroyed, forcing the cell to take on the complementary logic state; this process is irreversible. Fusible links are used in a similar manner in field-programmable logic arrays (see PLA). A fusible link is sometimes incorporated in a PROM or PLA to ensure that the data cannot be changed after being programmed. A similar technique is employed in some printer consumable items (e.g. toner cartridges) to ensure that they are not re-used.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
