Yes that can be done. You need to instrument the intermediate representation. A memory read will be represented by an Iex_Load expression and a memory write will be represented by a Ist_Store statement. Take a look at libvex_ir.h for a description of the IR and at the lackey tool for a simple instrumentation example.
