Abstract From the Canadian patent

This invention includes an algorithm, which detects and identifies the error in each memory address of the Reduced Specification Integrated Memory chips (RSIMC). RSIMC with the same error pattern will then be grouped together along with the Error Correction Apparatus (ECA) for assembly into memory modules. ECA employs the redundant Error Correcting Algorithm which enables the rejected fallout, audio grade, toy grade and other reduced specification memory chips to become computer grade compatible such that the, corrected RSIMC memory modules would function as normal memory modules for computer (or computer sub-systems) usages and applications.

Why it's free to use

  • Filed September 9, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 9, 2014.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 9, 2016.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
