Multi-Bank Non-Volatile Memory System with Satellite File System

摘要

A multi-bank non-volatile memory system is presented. A first of the banks has a main copy of the file system and each of the other banks has a satellite copy of the file system. The back end firmware of the controller executes a thread for each of the banks. After the boot process, during normal memory operations, each of the threads can operate using its own copy of the file system without interrupting the other threads in order to access the file system.
