Abstract

A method of generating an IC layout diagram includes dividing a column of NOR-type read-only memory (ROM) bit cells into a plurality of N-bit groups separated by isolation features, wherein each group includes the number of bits N greater than two, based on a ROM code programming pattern of the column, assigning one or more logic patterns to each N-bit group of the plurality of N-bit groups, and storing an IC layout diagram including the logic patterns in a storage device.
