Abstract
A dynamic bus system with a central precharge device is disclosed that utilizes a controller circuit with a one-shot generator and write synchronizing circuits in combination with logic output modules having pull-up/down devices. The issuance of the output enable (OE) signals is interlocked with the turn-off of the precharge. Thus, data is written to the dynamic bus only when the precharge device is inactive, avoiding bus collisions. The resulting circuitry not only ensures the precharging of the bus before the data write to the bus, but will allow the synchronized OE signals to be issued during the same clock phase as the precharge signal.
