Problems solved by technology

When the traditional solid-state hard disk starts, the chip will read the firmware from the fixed address of NAND FLASH. However, if the data is read from the fixed address for a long time or the firmware is continuously updated, the loss of this address will be more serious. The number of writes is limited, and as time goes by, the risk of NAND boot failure greatly increases, which greatly reduces the service life of the SSD; therefore, it cannot meet the demand

Embodiment Construction

[0042] In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific examples, but not limited thereto.

[0043] Such as Figure 1 to Figure 5 Specific examples shown, where, as Figure 1 to Figure 2 Shown prior art, such as figure 1 As shown, when the chip is started, the bootrom (chip) reads the firmware from the fixed address of the NAND particle. The fixed address has been predetermined in the bootorm and cannot be modified, which makes the chip fail in the future. Greatly increased; because the address is fixed and cannot be modified, when the address is read or written multiple times, the loss of NAND particles will increase, and the number of reads and writes of the particles is limited. If the number of reads and writes is too large, the lifespan will be greatly reduced , and ultimately affect the startup of the chip and the se...

Abstract

The invention relates to a method and a system for effectively prolonging the service life of NAND startup. The method comprises the steps that S1, starting a chip, and completing initialization; s2,reading address information of the firmware from the NAND particle fixed address X0; s3, judging whether reading is successful or not; if yes, entering S5; if not, entering S4; s4, selecting the nextfixed address Xn of the fixed address X0 for reading, and returning to the step S3; s5, reading the bootstrap program from the read address, and verifying the bootstrap program; s6, judging whether the verification is successful or not; if yes, entering S7; if not, returning to S4; s7, running firmware. Through two-stage mapping, the read fixed address is subjected to multiple backups, and firmware is separated from the storage address, so that repeated erasing and writing of the same address by NAND particles are reduced, the service life of chip NAND starting is prolonged, and the service time of the solid state disk is prolonged.

Description

technical field [0001] The invention relates to the technical field of NAND start-up of solid-state hard disks, and more specifically refers to a method and system thereof for effectively improving the service life of NAND start-up. Background technique [0002] Chips using Nand FLASH to start are widely used in solid-state drives. It not only has a fast start-up speed, but also reduces the cost of solid-state drives. When the traditional solid-state hard disk starts, the chip will read the firmware from the fixed address of NAND FLASH. However, if the data is read from the fixed address for a long time or the firmware is continuously updated, the loss of this address will be more serious. The number of writes is limited, and as time goes by, the risk of NAND startup failure increases greatly, which greatly reduces the service life of the SSD; therefore, it cannot meet the demand. Contents of the invention [0003] The purpose of the present invention is to overcome the d...
