Latest Patents

Wheelus's latest patents include a method of testing a cache tag memory array and an integrated circuit memory using fusible links in a scan chain. The first patent focuses on content testing and comparator testing of a tag section of a cache tag memory array. This method confirms the functionality of the tag section by performing specific tests. For content testing, each tag location is tested once, while comparator testing determines the functionality of the comparator within the cache tag memory array. The number of tests performed for the comparator testing is calculated as 2 times M plus 2, where M represents the number of bit positions in the tag location.

The second patent involves an integrated circuit memory that includes programmable fuses coupled to scannable flip-flops. These components are implemented in a scan chain and are used to program specific information about the integrated circuit memory, such as repair information, wafer lot number, and die position on the wafer. This innovation enhances the efficiency of package testing.
