摘要： 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.
