Abstract:	當快閃記憶體損壞時，其具有資料無法修復的先天缺陷，如何預防資料毀損已經成了一個必須具備的功能。特別在固態硬碟的使用上，如何預防硬碟故障所造成資料毀損已是一個重要的設計議題。本論文設計實現一個可以使用在固態硬碟(Solid State Drives, SSD)的高效能電源救援系統。本系統藉由高效能的能量儲存管理控制電路及搭配常見的鉭質電容來儲存電源，此方式可以改善早期使用超級電容之體積大與價格昂貴的缺點，並且以一個最簡化的單一充電與放電路徑來保護資料傳輸。在硬碟故障或異常斷電之無預警的狀況下，所提方法可以防止資料毀損或硬碟故障。 The flash memories have congenital defects that the data cannot be repaired when they are damaged. Thus, how to prevent data destruction has become a must-have feature. Especially when using the Solid State Drives (SSD), how to prevent the data destruction caused by a hard disk failure is an important design issue. In this thesis, a high-performance power rescue system used in solid state drives is designed and implemented. A high-performance energy storage management control circuit with some common tantalum capacitors is designed to store power. It can improve the drawbacks of the previously used super capacitors, such as bulky and expensive. Moreover, a most simplified charge and discharge system with a single path in the power bus is designed in the high-performance power rescue system to protect data transmission. In the hard drives failure or an unexpected power shutdown without warning status, the proposed method can prevent data damage or hard drive failure.
