Solid state drive encountering power failure and associated data storage method
First Claim
Patent Images
1. A solid state drive, electrically connected to a host, comprising:
- a control unit, for receiving data-for-writing from the host, and transforming the data-for-writing to data-for-storage;
a buffer unit, for storing the data-for-storage;
a multi-level cell flash memory, electrically connected to the control unit; and
a voltage detecting unit, for receiving a supply voltage, and issuing an informing signal when the supply voltage is lower than a predetermined voltage, whereinthe control unit proceeds a strong-page programming procedure for storing the data-for-storage to a blank area of the multi-level cell flash memory after receiving the informing signal.

Abstract
A solid state drive and its associated data storage method are provided. The data storage method comprising steps of: receiving data-for-writing from a host, and transforming the data-for-writing to data-for-storage; comparing a supply voltage and a predetermined voltage; and when the supply voltage is lower than the predetermined voltage, proceeding a strong-page programming procedure for storing the data-for-storage to a blank area of a multi-level cell flash memory.
