Testing system and testing method thereof
A testing system for a wafer having a plurality of flash memory dies is provided. The testing system includes a testing apparatus and a probe card coupled to the testing apparatus via a specific transmission line. The testing apparatus provides a testing requirement. The probe card includes a plurality of probes and a controller. The probes contact with at least one of the flash memory dies of the wafer. The controller writes a testing data to the flash memory die according to the testing requirement and reads the testing data from the flash memory die via the probes. The controller provides a testing result to the testing apparatus according to the read testing data.
1. A testing system for a wafer having a plurality of flash memory dies, comprising:
a testing apparatus, providing a testing requirement; and
a probe card coupled to the testing apparatus via a specific transmission line, comprising:
a plurality of probes, contacting with at least one of the flash memory dies of the wafer; and
a controller, writing a testing data to the flash memory die according to the testing requirement, and reading the testing data from the flash memory die via the probes,
wherein the controller provides a testing result to the testing apparatus according to the read testing data,
wherein the controller performs an error checking and correcting procedure for the read testing data, to obtain the testing result.
2. The testing system as claimed in claim 1 , wherein the testing apparatus determines whether the flash memory die is normal according to the testing result.
3. The testing system as claimed in claim 1 , wherein the specific transmission line is a universal serial bus (USB) transmission line.
4. The testing system as claimed in claim 1 , wherein the specific transmission line is a universal asynchronous receiver/transmitter (UART) transmission line.
5. The testing system as claimed in claim 1 , wherein the controller is implemented in an integrated circuit (IC).
