ABSTRACT:
A controller and method for refreshing a display device with data linearly stored in a video memory having a row addressable memory array and serial access memory are disclosed. The circuit for controlling the video memory includes a row address generator for addressing a row of data in the memory array. A circuit is provided for initiating a split row transfer of a half addressed row of the memory array to the corresponding half of the serial access memory while data are shifted out of the other half of the serial access memory. A tap pointer generator is also provided to alternatively point to the different halves of the memory array rows.
