known-good die

Chips that have been fully tested before being placed into their packages. Chips used in ceramic-based multichip modules (MCMs) are typically fully tested beforehand, because the ceramic substrates are costly to replace if the final package is faulty because of a bad chip. See MCM and known-good software.
