I notice there is a little confusion about storing analog or digital in Flash Memory. Flash memory can only store digital data, it cannot store analog data.

I think I understand why it is confusing. In the patent, Woody describes the processing of voice, and after the Analog-to-Digital conversion, he still refers to it as analog. I think this is a mis-statement that he did not mean to make. After analog is converted to digital, you should refer to it as "sampled data", or "uncompressed data", but referring to it as analog just makes it confusing to people. It is no longer analog, it is digital, but uncompressed. Yes you can store uncompressed digital data in Flash, and that is where he states it is not efficient, so he processes it through the DSP to compress it before it is stored. But he never meant to imply that he can store true analog data in a Flash memory, because that is not possible. Never has been possible.
