  • Dynamic memory device with refresh circuit and refresh method
    Patent number: 5875143
    Abstract: A refresh circuit (230) and a method for the refresh of dynamic memory devices (201) are described where the rows to be refreshed are determined by a logical function and by a reference address (223). The availability of refresh signals (215) for the rows at the outputs (217) of a decoder (214) is determined by control logic (224) which is connected to an address generator (212) and to a reference register (222) which contains a reference address (223). By supplying the reference address (223) to the refresh circuit (230) it is possible to determine which rows are to be refreshed. The memory array (210) of the dynamic memory device (201) can be refreshed partially and energy consumption for the refresh can be reduced.
