Abstract

Abstract Electronic systems using certain non-square dies, such as triangular dies, greatly elongated rectangular dies, parallelogram dies, trapezoidal, and the like, are able to be laid out in the area of a circular semiconductor wafer more "efficiently" than square dies. Further, a peripheral area of these certain non-square dies is advantageously increased relative to the area contained within the peripheral area, to accommodate increased I/O connections to the active elements of the die.
