Data bus system and method in which a plurality of data lines extend between functional units, and data signals having a predetermined voltage swing are sent from one unit to the others over the data lines. The sending unit also generates a reference voltage at the mid-point of the voltage swing, and this reference voltage is sent to the other units on a reference line for comparison with the signals on the data lines.

Low noise, high performance data bus system and method

A semiconductor device where an emitter material composition and doping profile produces an electron gas in a base adjacent a band offset heterojunction interface, the electrons in the electron gas in the base are confined under bias by a low barrier and the ballistic carriers have their kinetic energy controlled to prevent intervalley scattering by an electrostatic barrier that under influence of bias provides an essentially level conduction band in the portion of the base adjacent the collector.

A transposable memory architecture for providing equally fast access to stored data in two or more dimensions. This architecture is provided by orthogonal wiring of access devices, word lines and bit lines with independent random accessing capability for data in each direction. The transposable memory architecture (TMA) cell directly inplements the TMA architecture using only one access device per dimension of access. This invention also describes multiple transposable memory architecture (MTMA) device for additional data path flexibility. The read and write operations described provide access and cycle times approximately equivalent to those for a convention one-dimension RAM.
