Description
Technical field
The invention belongs to the memory device field, relate in particular to a kind of electronic hard disc and electronic equipment.
Background technology
Along with the development of infotech, memory devices such as hard disk also more and more are widely used, and traditional hard disk adopts disk as storage medium, by the spinning movement of disk, realize data storage.This traditional hard disk is subjected to the influence of external environment easily, and factors such as vibrations, temperature all can influence the normal operation of this hard disk.For fear of the influence of environmental factors such as vibrations, temperature to hard disk, people have brought into use electronic hard disc in the occasion that some need.This hard disk adopts flash array (Flash) as storage medium, stores data with the storage mode that does not have the machinery motion, thereby has characteristics such as anti-vibration and anti-high and low-temp.At present, general when the user need delete data in the electronic hard disc by using external software, the data in this hard disk are partly or entirely deleted.But make when carrying out deleted data in this way, the speed of deleted data is rapid inadequately, does not reach certain user's demand.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of electronic hard disc, is intended to solve existing electronic hard disc deleted data problem rapidly inadequately.
The embodiment of the invention is achieved in that a kind of electronic hard disc, and described electronic hard disc comprises:
Main control chip is used to receive the data self damaging order, according to described data self damaging order output pulse enable signal;
Chromacoder is used for described pulse enable conversion of signals is become data self-destruction trigger pip, and exports described data self-destruction trigger pip;
Flash array is used to store data; And
The high voltage controller links to each other with described flash array and described chromacoder respectively, when being used to detect described data self-destruction trigger pip, in described flash array, described flash array is burnt action of high voltage.
Another purpose of the embodiment of the invention is to provide a kind of electronic equipment, and described electronic equipment comprises at least one electronic hard disc, it is characterized in that, described electronic hard disc comprises:
Main control chip is used to receive the data self damaging order, according to described data self damaging order output pulse enable signal;
Chromacoder is used for described pulse enable conversion of signals is become data self-destruction trigger pip, and exports described data self-destruction trigger pip;
Flash array is used to store data; And
The high voltage controller links to each other with described flash array and described chromacoder respectively, when being used to detect described data self-destruction trigger pip, in described flash array, described flash array is burnt action of high voltage.
In an embodiment of the present invention, by using a high voltage controller, and utilize main control chip to control this high voltage controller, thereby can utilize action of high voltage, make Flash burn Flash, thereby can destroy the data that are stored among the Flash rapidly in Flash.
Description of drawings
Fig. 1 is the structural representation of the electronic hard disc that provides of the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In an embodiment of the present invention, by using a high voltage controller, and utilize main control chip to control this high voltage controller, thereby can utilize action of high voltage, make Flash burn Flash, thereby can destroy the data that are stored among the Flash rapidly in Flash.
Fig. 1 shows the structure of the electronic hard disc that the embodiment of the invention provides, and this electronic hard disc can be the memory device of electronic equipment.Certainly, electronic equipment can be computing machine, video recorder, televisor or set-top box etc.
When main control chip 11 receives the data self damaging order that the user sends, produce a pulse enable signal, and this pulse enable signal is exported to chromacoder 12.Chromacoder 12 is changed this pulse enable signal, exports a data self-destruction trigger pip and gives high voltage controller 13.When high voltage controller 13 detects this data self-destruction trigger pip, in Flash14, Flash14 is burnt action of high voltage, thereby the data that are stored among the Flash14 have also just been destroyed.
When the electronic hard disc operate as normal, when promptly main control chip 11 does not receive the data self damaging order that the user sends, by motherboard power supply Flash14 is powered, so that the Flash14 operate as normal.
As embodiments of the invention, this data self-destruction trigger pip is a level signal, and high voltage controller 13 is a relay, and the one contact links to each other with a high voltage output line of motherboard power supply, and its another contact links to each other with the Flash normal working voltage output line of motherboard power supply.When receiving data self-destruction trigger pip, relay is communicated with high voltage, and high voltage acts on Flash14 by relay, and Flash14 is burnt.When the electronic hard disc operate as normal, relay is communicated with the Flash normal working voltage, and this voltage acts on Flash14 by relay, makes Flash14 energy operate as normal.As embodiments of the invention, the value of Flash normal working voltage is+3.3V that high-tension value is+12V.
In order to send the data self damaging order better, in electronic hard disc, can also comprise data self damaging order trigger, this data self damaging order trigger is connected with main control chip, to main control chip input data self damaging order.This data self damaging order trigger can be for being arranged at the button on the electronic hard disc, perhaps wireless signal receiver.
In an embodiment of the present invention, by using a high voltage controller, and utilize main control chip to control this high voltage controller, thereby can utilize action of high voltage, make Flash burn Flash, thereby can destroy the data that are stored among the Flash rapidly in Flash.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
