The size of the RAM is 132 X 65= 8580 bits. Figure 5 is a description of the GDDRAM address map. For mechanical flexibility, re-mapping on both Segment and Common outputs can be selected by software. For vertical scrolling of display, an internal reg- ister storing the display start line can be set to control the portion of the RAM data to be mapped to the display. Figure 5 shows the case in which the display start line register is set to 38h.
