Specialty memory devices has been a driving force in innovative system design. Specialty devices are combinations of memory and logic, other than the microcomputer combination, that address a wide variety of applications. They have traditionally offered solutions to critical performance requirements that were otherwise prohibitively expensive or not feasible. As system speeds and integration levels of integrated circuits change, specialty memory devices follow suit, while gaining new applications, and larger markets.

In cellular systems, voice quality should be the first concern, then capacity, then cost. Otherwise by increasing system capacity, voice quality will be degraded. This paper will use the radio capacity formula to measure the capacity and deduce many findings.

The technology and material choices available for MCMs are discussed in terms of a cost-yield model. The basic building blocks of MCMs are presented and viewed in terms of the number of processing steps, defect density and processing costs.

Multichip modules (MCMS) employ uncased chips mounted and interconnected on multilayer circuit boards. The interconnect is fabricated using alternate layers of conductor and dielectric thin films connected by vias through the interlayer dielectric. Depending upon the performance, assembly flexibility and cost considerations, various approches can be used for fabricating and packaging MCMs. A number of circuit board technologies and packaging schemes applicable to different MCM applications are summarized in this paper. An effort is made to classify these MCMs into low, moderabe or high circuit density types. Several examples are provided to point out the suitability of various MCM approaches to the selected applications.

Serial EEPROM devices are finding their way into more and more microcontroller applications. Almost any microcontroller system can find a use for EEPROM to store necessary software parameters or to provide read/write flexibility to the product. For the most part, semiconductor manufacturers have not found cost effective means for processing EEPROM on the same chip as the microcontroller. As a result semiconductor manufacturers such as National Semiconductor and ICT have developed families of low density serial EEPROMs targeted for use in microcontroller applications. The serial EEPROM provides microcontroller system designers with a simple interface to accessing small amounts of nonvolatile memory with virtually no sacrifice to board space.
