"For example, a store may be buffered in a cache that later writes."

Type of change: Clarification.

Explanation:

1. The intent of the example (if I'm reading between the lines correctly) is that stores may buffer in a cache to later write, not that stores trigger reads.
2. A store to a cache need not necessarily be satisfied by a read operation to fill the cache, if the cache tracks data valid / dirty at a small enough granule and/or gathers enough stores to fill a data valid / dirty granule.

The intent was to describe that a store may result in a read operation initially. Think of a store to a WB cache, which first performs a read operation on memory.

It is true that the store may be buffered in the cache and then the cache may perform a write operation. But this comment was meant simply to illustrate the above behavior (among many others).

Sure, was just a suggestion in example text.
