How does the lock bit of the CY7C63001a work?

Question: All programmers from HI LO have something called a "Lock Bit" option for code protection. Is there such a feature in the HI LO programmer supported by Cypress for the M8 parts?

 

Answer:

The HI LO programmer shipped by Cypress has a similar feature known as the Security button on the programmer application. This feature destroys the security fuse and then the device is no longer readable by the application and hence is secure.
