摘要： An address generation system and method is provided for internally storing and thereafter producing an address to be sent to a memory device. The address that is stored need not be sent from an external address bus at each clock cycle, but the processing can remain internal to the memory device. The burst-block starting address can be stored in the mirror register (52) and output from a selector circuit, such as a multiplexer (54) when that address is chosen. Otherwise, the multiplexer can simply perform its normal operation of selecting between an address pointed to by a counter (60), the external address (ADDR, IN), or the incremented counter output, based on the state of the external counter control signals. The system includes a mirror register, a counter, and a multiplexer that selects either the mirror register stored address or the internally processed address.
