A pattern data development/generation apparatus includes a pattern generation circuit for obtaining a share of a target pattern in each square and outputting share data in reading pattern design data, decoding pattern data including a pattern shape, a pattern position and a pattern size, and assigning the decoded output data to the squares having an appropriate size as a unit, a pattern memory for holding a predetermined range of the share data generated by the pattern generation circuit, and a pattern memory readout circuit for reading out the share data of each square.
