What will be the benefits of SPMT over existing memory technologies?
The mobile device market, particularly the handset market, is under intense competitive pressure to increase functionality while maintaining or reducing overall system cost. One major consideration in designing a mobile device centers around what type of memory will be used by the system. All of the current memory architectures have varying degrees of tradeoffs that affect overall system cost and performance. All currently available memory chips have a parallel interface that requires a high number of connections (pins) to achieve a minimum performance level for basic mobile device functionality. This is analogous to a carpool lane (serial) versus the remaining lanes (parallel) on a major highway. The carpool lane has more occupants (data) per car and moves at a greater speed (bandwidth) while the other lanes (parallel) have more lanes but fewer occupants (data) and move much slower (bandwidth) – particularly during rush-hour. In other words, you can get a lot more data from a high-spe
