Here is a simpler explanation about how the words "memory" and "storage" are COMMONLY used (in my experience):

As verbs, "memorizing" and "storing" are often used as synonyms. As nouns, "memory" and "storage" are often used as synonyms, indicating a place to store information for later use.

In common use by non-technical people, "memory" is all the stuff you know but are not thinking about now. In common use in computer literature, memory is all the information and data that a computer knows but is not currently processing (stored in CPU registers, RAM, and external archival storage hardware) AND the location used to store this information (including RAM memory, core memory, disk memory, drum memory, etc.), which adds to the confusion. Storage is the process of memorizing this information, and the place that it is stored (also called memory). When using these words it is necessary to include extra words to distinguish them from each other (such as RAM, flash, disk, etc.), because they ARE used in many disparate ways in the trade literature and documentation.

I hope that makes it a little less confusing, and demonstrates that I did initially use these words correctly when asking for information to help determine the cause of the "out of memory" condition when displaying PDF files.

Kindles (especially the newer models) have plenty of flash memory (the USB drive), but not enough RAM memory (especially when rendering large complex PDF files).
