Abstract
Illustrative embodiments provide a mixed programmable and application-specific integrated circuit, a method of using the mixed programmable and application-specific integrated circuit and a method of making the mixed programmable and application-specific integrated circuit. The mixed programmable and application-specific integrated circuit includes at least a portion of a programmable transistor array that is programed after fabrication. The programmable transistor array can include at least another portion that is mask programed during fabrication.
Claims21
