Security feature of M8 Programmers

Question: Using Hi-Lo system's All-11 programmer, the programmer has "Lock Bit" option for code protection. Would you explain briefly how the lock bit of CY7C63001a works and how secure it is?



The HI Lo programmer shipped by Cypress has a similar feature like the Security button on the programmer application (Cystart). This button allows the user to destroy the security fuse making the chip unreadable by the application. There by making it secure from over writing or reading. We have not worked with all the programmers provided by HI LO. But the concept is similar. Please contact the manufacturer of the programmer for further information on this feature.
