 ## Memory Models
 
 The `MemoryModel` has the same interface as a `Memory`, but is non-synthesizable and uses a software-based `SparseMemoryStorage` as a backing for data storage. This is a useful tool for testing systems that have relatively large memories.

+The `MemoryStorage` class also provides utilities for reading (`loadMemString`) and writing (`dumpMemString`) verilog-compliant memory files (e.g. for `readmemh`).
