Abstract
An integrated circuit including a serial interface (12) having a nonvolatile memory (30) coupled to a and configuration of circuit boards and entire systems. A configurable circuits (10) containing switches, resistors, capacitors or digital logic devices has an unique identification code and is electrically configured by connection to a nonvolatile memory (30). An interrogation shift register (38) and a configuration data shift register (36) are serially connected to receive a serial bit stream (50) containing an interrogation code section and a configuration data section. The interrogation code, which is identical to the identification code of a selected one of the configurable circuits, is compared with the circuit identification code to provide a match pulse (42) that enables a program signal to initiate transfer of data from the data shift register (36) to the nonvolatile memory (30).
