ABSTRACT:
A counter circuit is disclosed. The circuit has a first tri-state inverter for receiving data bits and their components. It includes a first tri-state latch for receiving the data bits and their complements, connected to the output of the first tri-state inverter. It has a second tri-state inverter for receiving the data bits and their complements that is connected to the output of the first tri-state latch. It includes a second tri-state latch for receiving the data bits and their complements. The second tri-state latch is connected to the output of the second tri-state inverter. Its output is the output of the circuit, and, its output is fedback to the first tri-state inverter. Such a circuit is useful in setting an internal address of a dynamic memory device during a CBR cycle.
