Title
(EN) Method for prewarning service life of semiconductor storage medium and system and device using same
(ZH) 半导体存储介质的寿命预警方法、系统及装置
Abstract
(EN)
The invention provides a method for prewarning service life of semiconductor storage medium and a system and a device using same. The method comprises the following steps: acquiring the service life information of semiconductor storage medium; and carrying out prewarning according to the acquired the service life information. The method adopts a prewarning mode to realize service life prompt of the semiconductor storage medium, and can give an alarm before the semiconductor storage medium reaches a use limit so that a user can learn the time at which the service life of the semiconductor storage medium reaches limit during use; thus, backup of important data can be carried out in time before storage equipment aging, thereby protecting data security and avoiding data loss.
