Segment Reporting [Abstract]

SEGMENT REPORTING

12. SEGMENT REPORTING

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker. The Company has two reportable segments: standard products and other products, which consist primarily of custom and foundry products and revenues from the license of patents. The chief operating decision maker evaluates segment performance based on revenue. Accordingly, all expenses are considered corporate level activities and are not allocated to segments. Therefore, it is not practical to show profit or loss by reportable segments. Also, the chief operating decision maker does not assign assets to these segments. Consequently, it is not relevant to show assets by reportable segments.
