ABSTRACT:
In a video-type computer system and the like, an improved memory circuit is provided for adapting the system to CRT screens having different resolutions. The memory circuit includes a bit-mapped RAM unit or chip having sufficient cells to accommodate any CRT screen sought to be used, and also a serial shift register having taps at a plurality of different locations corresponding to different columns of cells in the RAM unit. When the RAM unit is in serial mode, a row of data is transferred into the serial shift register. Then the column address applied to the RAM unit is used to instruct and actuate a suitable decoder circuit to select the tap appropriate to unload the portion of the serial shift register containing the data bits of interest.
