ULTRA LOW PIN COUNT INTERFACE FOR DIE TESTING

摘要

An apparatus, a method and a system to test a device. An input/output (I/O) block communicates with an external tester to receive test data and to send test result using first and second communication modes. A logic block parses the test data. A memory stores microcode from the parsed test data. The microcode contains a test program to test a circuit. A controller executes the test program.
