ABSTRACT:
A bit-read apparatus includes a first decoder and N multiplexers, each having Q output nodes and Q pull-ups coupled thereto. Respective multiplexers have M selectors coupled to N×M respective select lines and register-file cells. The selectors are in Q groups coupled to respective output nodes. Each multiplexer has a logic gate with inputs coupled to respective multiplexer output nodes. A second decoder is coupled to an N+1th multiplexer having R output nodes and R pull-ups coupled thereto. The N+1th multiplexer also has N selectors, coupled to respective select lines of the second decoder and respective output logic gates of the N multiplexers. The N selectors are in R groups coupled to the R nodes. An output logic gate for N+1th multiplexer has R inputs coupled respectively to the R nodes. Each pull-up of the multiplexers drives its respective multiplexer output node responsive to an address-bit signal.
