Further, described power module comprises four power supply chips, nand flash memory array has flash memory input and output power interface and flash memory storage power interface, first power supply chip produces the first voltage and the first voltage is inputted the first dram chip and the second dram chip, second source chip produces the second voltage and the second voltage is inputted the first main control chip, 3rd power supply chip produces tertiary voltage and tertiary voltage is inputted nand flash memory array by flash memory storage power interface, 4th power supply chip produces the 4th voltage and the 4th voltage is inputted nand flash memory array by flash memory input and output power interface.
Further, described first voltage is 1.5V, and the second voltage is 1.2V, and tertiary voltage is 1.8V, and the 4th voltage is 3.3V.
Further, described responding device is LED or hummer.
The beneficial effects of the utility model are:
1, by detecting the service life state of solid state hard disc, when solid-state disk service life exceedes life-span early warning threshold values, solid state hard disc constantly flashes LED, starts to back up the data in solid state hard disc to warn user.Therefore, the utility model solid state hard disk secure is high.
2, the utility model is provided with two dram chips, avoids adopting single DRAM and main control chip circuit design and causes the data writing NAND to occur the situation of mistake, and main control chip is more reliable and high efficiency writes correct data to NAND.
Accompanying drawing explanation
A kind of solid state hard disc electrical block diagram with life-span warning function that Fig. 1 provides for the present embodiment.
Embodiment
Be described further below with reference to accompanying drawing 1 pair of the utility model, but protection domain of the present utility model should do not limited with this.For convenience of description and understand the technical solution of the utility model, below illustrate that the orientation that the noun of locality used all is shown with accompanying drawing is as the criterion.
As shown in Figure 1, a kind of solid state hard disc with life-span warning function that the present embodiment provides comprises power module, main control chip, dram chip, nand flash memory array and responding device.Power module is connected with main control chip, dram chip, nand flash memory array respectively, and main control chip is connected with dram chip, nand flash memory array respectively, and main control chip is also connected with responding device by DASP pin.Wherein, responding device can be hummer or LED.
Wiping/write operation the counting of main control chip statistics nand flash memory array, and main control chip is also analyzed this counting and whether is exceeded solid-state disk service life early warning threshold values, on the one hand, if exceed solid-state disk service life early warning threshold values, then main control chip produces action by DASP pin trigger-response mechanism, what such as triggering hummer continued sends sound, triggers LED and continues to flash.Certainly, responding device can also be that other produce the device of early warning signal.On the other hand, if do not exceed solid-state disk service life early warning threshold values, main control chip does not produce action.
The solid state hard disc that the present embodiment provides is by detecting the service life state of solid state hard disc, and when solid-state disk service life exceedes life-span early warning threshold values, solid state hard disc constantly flashes LED, starts to back up the data in solid state hard disc to warn user.Therefore, the utility model solid state hard disk secure is high.
As preferably, solid state hard disc comprises two dram chips, power module is connected with main control chip, the first dram chip, the second dram chip, nand flash memory array respectively, main control chip respectively with the first dram chip, the second dram chip, nand flash memory array are connected, and main control chip is also connected with LED by DASP pin.
Power module comprises four power supply chips, nand flash memory array has flash memory input and output power interface and flash memory storage power interface, first power supply chip produces the first voltage and the first voltage is inputted the first dram chip and the second dram chip, second source chip produces the second voltage and the second voltage is inputted the first main control chip, 3rd power supply chip produces tertiary voltage and tertiary voltage is inputted nand flash memory array by flash memory storage power interface, 4th power supply chip produces the 4th voltage and the 4th voltage is inputted nand flash memory array by flash memory input and output power interface.Wherein, the first voltage is 1.5V, and the second voltage is 1.2V, and tertiary voltage is 1.8V, and the 4th voltage is 3.3V.
The present embodiment is provided with two dram chips, avoids adopting single DRAM and main control chip circuit design and causes the data writing NAND to occur the situation of mistake, and the first main control chip is more reliable and high efficiency writes correct data to NAND.
The treatment scheme of solid state hard disc error in data protection is as described below:
First the data of npairpage are write, and by this data in advance with n-1, n-2, n-3, n=1, n+2, the form of n+3 is loaded into the second dram chip, and the first main control chip analyzes the data mode of the second dram chip, on the one hand, if mistake does not appear in the data mode of the second dram chip, then the first main control chip wipes the data be stored in dram chip; On the other hand, if mistake appears in the data mode of the second dram chip, again write the dram chip data being configured to nand flash memory array.After completing the process of data, turn back to the first step, namely first write this step of data of npairpage, until correct data all write nand flash memory array.First dram chip stores physical logic link table, and the first main control chip can according to the storage data manipulation nand flash memory array of the first dram chip.Traditional solid state hard disc does not have error protection function; and circuit design only adopts single dram chip; therefore the utility model is provided with two dram chips; second dram chip store both program data; whether main control chip is analyzed the second dram chip in advance exists misdata and determines that the second dram chip is the need of re-writing data, and the first main control chip can write data respectively by the first dram chip and the second dram chip to nand flash memory array afterwards.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned embodiment and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this instructions, these terms just for convenience of description, do not form any restriction to the utility model.
