Abstract
The preferred embodiments described herein provide a memory device and method for storing and reading a file system structure in a write-once memory array. In one preferred embodiment, a plurality of bits representing a file system structure is inverted and stored in a write-once memory array. When the inverted plurality of bits is read from the memory array, the bits are inverted to provide the file system structure bits in their original, non-inverted configuration. With this preferred embodiment, a file system structure can be updated to reflect data stored in the memory array after the file system structure was written. Other preferred embodiments are provided, and each of the preferred embodiments described herein can be used alone or in combination with one another.
