Embodiment 1

[0024] In one embodiment, as figure 1 As shown, the solid-state hard disk 10 includes a flash memory controller 200, a flash memory 300, a power manager 400, and a power supply device 100. The power manager 400 and the flash memory 300 are connected in parallel to form a control branch. The power supply device 100, the control branch, and the flash memory controller 200 are connected in sequence. In one embodiment, the flash memory 300 includes 1 or more than 2, the number of the power manager 400 is the same as that of the flash memory 200, and each of the power management modules is associated with a flash memory in parallel.

[0025] The flash memory controller 200 is used to control the flash memory 300 to perform read, write and delete operations;

[0026] The power supply device is used to supply power to the flash memory 300 and the flash memory controller 200;

[0027] The flash memory 300 is used for storing data.

[0028] The power supply device 100, the flash me...

Embodiment 2

[0053] This embodiment is basically the same as Embodiment 1, as Figure 4 As shown, the solid-state hard disk 10 of this embodiment also includes at least a flash memory controller 200, a flash memory 300, and a power manager 400. The difference lies in that the power manager 400 and the flash The memory 300 is connected in parallel to form a control branch, and the power supply device 100, the control branch, and the flash memory controller 200 are connected in sequence. However, in Embodiment 2, the power supply device 100 , the control branch, and the flash memory controller 200 are connected sequentially in the order of the power supply device 100 , the flash memory controller 200 , and the control branch.

[0054] The solid-state hard drive of the present invention plays the role of adjusting the power supply voltage by configuring the power supply manager 400, and can protect the flash memory from being burned out when the power supply voltage is too high; , the stored...

Abstract

A solid state hard disk is disclosed. The solid state hard disk is characterized by comprising a flash memory controller, a flash memory, a power supply device and a power manager, wherein the power supply manager and the flash memory are connected in parallel to form a control branch, the power supply device, the control branch, the flash memory controller is connected in turn or the power supplydevice is connected in turn, and the flash memory controller and the control branch are connected in turn. The solid-state hard disk of the invention plays the role of regulating the power supply voltage by configuring a power supply manager, and the flash memory can be protected from being burned when the power supply voltage is too high; at that same time, the power management module has the function of storing power.

Description

technical field [0001] The invention belongs to the field of data storage and relates to a solid-state hard disk. Background technique [0002] Solid State Drive (SSD) mainly includes a flash memory controller (Flash management chip) and flash memory (flash memory, Flash chip). Compared with traditional hard disks, it has no mechanical structure, low power consumption, and shock resistance. , high stability, low temperature resistance and other advantages. [0003] Super Capacitor (SC) has the characteristics of large capacity, simple charging and discharging circuit, no charging circuit similar to rechargeable batteries, high safety factor, and maintenance-free for long-term use. The current power supply mode of the solid-state hard disk is that the power supply device supplies power to the flash memory controller first, and then the flash memory controller supplies power to the flash memory. After the power supply device supplies power to the flash memory controller, the...
