we are searching for a non volatile memory to storage an ID. Regardless of One-Time-Programmable, Multi-Time-Programmable, EEPROM, Memory based on eFuses or whatever. Main issue: LOW POWER! We don't have to storage many bits. 32 or 64 bits are enough. Technology: TSMC 90nm LP. Does anyone have a proposal where I can find such an IP?
I believe that TSMC ought to have a list of design partners
and IP on their web pages; I'd start there. The qualification
of nonvolatile memory, from scratch, is longer and more costly
than you may imagine.
Novocell, and whoever they became or came from, may have
something for you.
