Abstract
In the driver for driving display having an anode driver, a cathode driver, and memory portions of a semiconductor device of the invention, anode driver regions connected to the memory portions are laid out equally in the chip, and SRAMs and are arranged equally in the vicinity of each of anode driver regions so that drawing of wiring becomes easy and size of the chip is miniaturized.
Claims17
A pattern layout method of a semiconductor made in one chip with an anode driver, a cathode driver, and memory portions comprising the steps of:
- laying out drivers connected to the memory portions equally in the chip;
- and
- arranging each memory portion equally in the vicinity of each of the drivers.
A pattern layout method of a semiconductor device for drivers where plural output regions corresponding to one bit are arranged to constitute desired output bit group and made in one chip comprising the step of:
- arranging a plurality of the output group at periphery portion in the chip.
A pattern layout method of a semiconductor device constituting drivers for driving display where drivers, memory portions are made in one chip, the drivers arranging plural output regions corresponding to one bit to constitute output bit groups, the method comprising the steps of:
- arranging the drivers at periphery portion in the chip in the state of grouping by every desired output bit group;
- and
- arranging wirings connected to each output bit arranged at the periphery portion to circle fitting shape of the chip.
