How to detect damaged cells (NVM) - Integrity Check
864549Jun 22 2011 — edited Jun 22 2011Hi,
is there any way to detect damaged memory (NVM) ?
Is there any sample code for that purpose ?
I'm a bit concerned about the security of java card applets. The number of times you can update an NVM (non-volatile memory) is limited (~100,000 updates for E2PROM and FLASH). Hence I'm taking care to avoid over-stressing the NVM. However, what happens if this limit is reached? Will it result in corrupt data? So it could be a potential risk, especially if the applet is dealing with security?
What is the common practice to ensure no issues if memory is damaged?
