Abstract

The embodiments described herein can be used to enable one-time or few-time programmable memories to work with existing consumer electronic devices (such as those that work with flash—an erasable, non-volatile memory) without requiring a firmware upgrade, thereby providing backwards compatibility while minimizing user impact. As such, these embodiments are a viable way to bridge one-time or few-time programmable memories with existing consumer electronic devices that have flash card slots. These embodiments also allow future consumer electronic devices to be designed without updating firmware to include a file system customized for a one-time or few-time programmable memory.
