A memory circuit ( ) having features specifically adapted to permit the memory circuit ( ) to serve as a video frame memory is disclosed. The memory circuit ( ) contains a dynamic random access memory array ( ) with buffers ( ) on input and output data ports ( ) thereof to permit asynchronous read, write and refresh accesses to the memory array ( ). The memory circuit ( ) is accessed both serially and randomly. An address generator ( ) contains an address buffer register ( ) which stores a random access address and an address sequencer ( ) which provides a stream of addresses to the memory array ( ). An initial address for the stream of addresses is the random access address stored in the address buffer register ( ).
