摘要

近年来,闪存芯片的可靠性急剧下降。为了解决这一问题,提出了一种可靠的存储技术器件(MTD)设计,在器件驱动层解决这一问题,从而释放闪存管理软件/固件的设计复杂性,提高现有和未来产品的闪存管理设计的可维护性和可移植性。通过一系列基于现实轨迹的实验来评估所提出的设计,表明所提出的方法可以在有限的开销下显着提高闪存的可靠性。

A reliable MTD design for MLC flash-memory storage systems
The reliability of flash-memory chips has dropped dramatically in recent years. In order to solve this problem, a reliable memory technology device (MTD) design is proposed to address this concern at the device driver layer so as to release the design complexity of flash-memory management software/firmware and to improve the maintainability and portability of flash management designs for existing and future products. The proposed design was evaluated through a series of experiments based on realistic traces to show that the proposed approach could significantly improve the reliability of flash memory with limited overheads.
