A self-identifying scheme which permits a variety of integrated circuit semiconductor memory modules to inform a host processor as to each individual memory accessing speed or accessing time. Pre-encoded circuits within each memory module generate a coded signal when that module is selected by the host processor. The coded signal identifies the type of memory accessed, permitting the host processor to transfer information at a rate determined by the memory accessed.

An apparatus and method is disclosed for reducing flicker in an interlaced computer generated raster-scanned display. Several circuits and methods are described for implementing vertical filtering. In general, the data for a given pixel on the nth, nth+1, nth+2 . . . nth+N line is read from memory and convolved to provide data for a given pixel on a display line before pixel data for other pixels along these lines is read from memory.
