Abstract
An integrated circuit memory (140) includes programmable fuses (20) coupled to scannable flip-flops (25). The programmable fuses (20) and scannable flip-flops (25) are implemented in a scan chain, and are used to program specific information about the integrated circuit memory (140), such as for example, repair (redundancy) information, wafer lot number and wafer number, die position on the wafer, or any other information that would be useful during or after package testing.
