Abstract

A method and system for power loss protection are provided. The method for power loss protection is adapted to a data storage device. The data storage device comprises a controller, a non-volatile memory, a first pin and a second pin. The method for power loss protection comprises the following steps. Firstly, the data storage device receives an operating voltage required for the operation of thedata storage device by using the first pin. Then, when a power loss event occurs, the data storage device receives a flash voltage required for the non-volatile memory to write back data by using thesecond pin, in order that the non-volatile memory completes a data writing procedure.

Description

technical field [0001] The present invention relates to a power loss protection (Power Loss Protection, PLP) method and system, in particular to a power loss protection method and system for a data storage device (Data Storage Device). Background technique [0002] Usually, the way to solve data storage devices, such as solid-state hard drives (SSDs) due to abnormal power failure, is to add a power-off protection circuit on the end of the data storage device, and use the large power-off protection circuit in the power-off protection circuit. Capacitance allows the data storage device to obtain extended power at the moment of power failure, so that the non-volatile memory in the data storage device, such as flash memory (Flash Memory), can complete the data writing process. However, in this type of method, the cost of the data storage device will be increased due to the use of the bulk capacitor, and there is no effective way to provide protection for the cached data (Caching...
