Rapid development of MCM-based nonvolatile memory subsystems

Summary form only given. Information is presented describing a quick-turn multichip module (MCM) technology and its use in the creation of custom nonvolatile memory subsystems. The technology features a programmable MCM substrate as an off-the-shelf solution for rapid circuit development. Two unique applications are discussed in which new designs of EEPROM-based circuits were developed and assembled very quickly. In less than a month, the programs moved from the initial paper concept to assembled, tested, miniaturized hardware. One of the module types experienced a design iteration which was accomplished in less than two days, including upgrading already assembled production units with the design change.
