Address counter cell

Abstract From the Canadian patent

An address counter cell for use in burst mode operation in a synchronous DRAM is described which in response to a falling edge of a system clock simultaneously loads address inputs into an external address master latch and an internal address master latch, and further enables a multiplexer to select between the external and internal address inputs. In response to a subsequent rising edge of the system clock, the selected address input is then loaded into a low-output-load capacitance slave latch and is further provided to complementary output nodes. The signal from one of the output nodes is also fedback to circuitry for incrementing the selected address internally for subsequent clock …
