An apparatus includes a first circuit and a second circuit. The first circuit receives indications of first data that is associated with a first data set and second data that is associated with a second data set. The second circuit is coupled to the first circuit to cause the first circuit to in a first mode, communicate indications of the first data to an output terminal in synchronization with a first phase of a clock signal and communicate indications of the second data to the output terminal in synchronization with a second phase of the clock signal. In a second mode, the second circuit causes the first circuit to communicate the indications of the first data to the output terminal in synchronization with the first phase and prevent communication of the second data during the second phase.

Circuit and technique to stall the communication of data over a double pumped bus

A ROM or other memory may include two or more partitions and a precharge circuit. Each of the partitions may be coupled to separate sets of output conductors, to which the precharge circuit may be coupled. The precharge circuit may precharge the conductors of the partition to be read, while not precharging the other conductors. In one embodiment, the precharge may be to a voltage representing a binary value. In one implementation, the non-precharged conductors may be held to a predetermined voltage different from the voltage to which the precharged conductors are precharged. The predetermined voltage may represent the opposite binary value to the binary value represented by the precharge voltage. The ROM may also include an output circuit which may, in certain embodiments, comprise a logic circuit which logically combines the signals on respective conductors from each partition to provide output signals from the ROM.
