I am looking for SD (Secure Digital) memory that can be programmed only once. Basically, once programmed, it cannot be erased. I searched the web, but I did not find any. Please let me know if you are aware of such technology. Thanks.

Can you explian what you are trying to use this for, and how secure, and how large, the OTP aspect needs to be.
Is it to prevent accidental corruption, or does this hold unique IDs that must remain secure, or is it a high revenue/high volume product you want to protect from rampant cloning (or virus/tampering) ?

Hi Jim,
I am trying to keep people from accidentally erasing the contents of the microSD. Basically, once it is programmed, I want the data to remain there, and not erased or programmed again. This is for a product, yet not a mass produced product. The size I need is 512MB. The microSD will not hold unique ids. Thanks.
