自修复系统和方法
摘要：
随着存储容量的增加，三维掩膜编程只读存储器（3D-MPROM）的测试时间变得很长，成本很高。相应地，本发明提出一种自修复系统。3D-MPROM的大部分数据在出厂时未被检测，而在使用现场被检测和修复。该系统含有一播放器。内容通过网络等通讯手段逐次传输至播放器的可重复写存储器（RWM）中。一段时间后，用户收到存储上述内容集合的3D-MPROM。播放器对其数据进行检测。如果发现错误数据，则从RWM处获取相应的正确数据。
摘要（英）：

The present invention discloses a self-repair system for three-dimensional mask-programmed read-only memory (3D-MPROM). Most of the 3D-MPROM data are not checked in the factory, but checked and repaired in the field. This self-repair system comprises a playback device with a re-writable memory (RWM). The RWM temporarily stores new contents. After a user receives a 3D-MPROM card storing the same contents, the playback device checks the 3D-MPROM data. When bad data are detected, the good data to replace the bad data are fetched from the RWM.
