摘要:

在对智能卡的存储器进行数据写入操作过程中,电源触点的掉电会破坏智能卡中存储的数据的完整性。本文针对这一问题,提出了一种面向耗损均衡的数据备份机制。实际应用表明,该机制可以有效地解决智能卡数据的完整性,同时能够有效地延长智能卡的使用寿命。

Abstract:

While writing data into the memory of smart cards, the power loss of the VCC contact point will cause the problem of data inconsistency. To address th  is problem, a wear-leveling-oriented data backup mechanism is presented in this paper. The actual practice shows that this mechanism not only effectively solves the data inconsistency problem, but also significantly extends the lifetime of smart cards.
