ZDNet UK took advantage of a recent visit to Bletchley Park to uncover some of the thousands of items of IT heritage that the National Museum of Computing has in store
Anamartic wafer memory
One of the ironies of computer memory is that multiple chips are made on one silicon wafer, expensively cut up and packaged, and then used next to each other in large numbers. Why not wire the chips together on the wafer, linking past ones that don't work, and just use that? That was the thinking by Ivor Catt, a British inventor, who sold his idea to Sinclair Research — thence a company called Anamartic, which got the results into production.
Unfortunately, by the time the product hit the market in 1989, the cost of individual chips from the Far East was so low that there was no advantage in using what had proved to be a reasonably expensive way of doing things and Anamartic closed three years later.
