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.

摘要： This invention relates to an apparatus, a memory controller and a system for upgrading firmware stored in a non-volatile memory, in phases, and restoring firmware in-situ to compensate for failed firmware upgrades. In various embodiments, the apparatus, memory controller and system can upgrade and restore the firmware as the non-volatile memory remains functioning. In one embodiment, a multi-mode memory controller includes a firmware selector for selecting a first copy of firmware for accessing in a functional mode, and for selecting a second copy of the firmware for upgrading in an upgrade mode. It also can include a phased upgrade controller being configured to access the first copy in the functional mode coincident or substantially coincident to replacing at least a portion of the second copy with at least a portion of an upgrade firmware in the upgrade mode.

摘要： A re-programmable non-volatile memory system, such as a flash EEPROM system, having its memory cells grouped into blocks of cells that are simultaneously erasable is operated to perform memory system housekeeping operations in the foreground during execution of a host command, wherein the housekeeping operations are unrelated to execution of the host command. Both one or more such housekeeping operations and execution of the host command are performed within a time budget established for executing that particular command. One such command is to write data being received to the memory. One such housekeeping operation is to level out the wear of the individual blocks that accumulates through repetitive erasing and re-programming.

摘要： A non-volatile memory device is provided with a controller and includes method that controls memory operations and to emulate the memory and communication characteristics of a legacy memory device. In this way, the memory device is compatible with a host that was originally designed to operate the legacy memory device. In particular, the controller performs the emulation to the host taking into account differences such as multibit memory, error correction requirement, memory support of overwrites, and erasable block sizes.
摘要翻译：非挥发性存储器件具有控制器，并且包括控制存储器操作并模拟传统存储器件的存储器和通信特性的方法。以这种方式，存储器设备与最初设计用于操作传统存储设备的主机兼容。特别地，控制器考虑到诸如多位存储器，错误校正要求，覆盖的存储器支持以及可擦除块大小之类的差异，对主机执行仿真。
