Abstract: An integrated circuit capable of dual configuration of data flow and operable in a plurality of operational modes is provided. The circuit includes eight corner pins, wherein the eight corner pins comprise a first corner pin and a second corner pin on each side of the circuit in each of four side sets, wherein a first corner pin of one side of the circuit is proximate and adjacent to a second corner pin of an adjacent side counterclockwise from the first corner pin and together constitute a paired corner set, each paired corner set comprising a differential input and a differential output.

Abstract: A digital memory characterized by a plurality of memory cells arranged into a matrix having rows and columns; a row activation circuit for concurrently activating all of the rows of the matrix; and column activation means for concurrently applying either a reset signal or a preset signal to the columns of the matrix. The column activation circuit can include a plurality of digital switches coupled to reset and preset lines associated with each column of the matrix; and reset/preset logic which control the digital switches to selectively couple the reset and preset lines to a constant current source. A complementary, multi-emitter flip-flop memory cell is formed on a semiconductor substrate and includes "riser" portions.
