  • Patent number: 6175535
    Abstract: A cycle control circuit for use with a memory device subarray and method of operation thereof. The cycle control circuit includes a previous address buffer for storing a last accessed address of the subarray and an address comparator for comparing a current requested address with the last accessed address in the previous address buffer. The cycle control circuit also includes a cycle counter, coupled to the address comparator, that receives a control signal generated by the address comparator and, in response thereto, modifies a reset operation of the subarray. In another aspect, the method includes applying an address to the subarray and generating control signals for the subarray to produce a data output in response to the address. After producing the data output, the applied address is stored. Next, a new address is received and the new address is compared to the stored address.
