Embodiment

[0025] As shown in Figure 1, the structural block diagram of the present invention is composed of a FLASH hard disk controller 1 and several FLASH memory card circuits 2. The FLASH hard disk controller 1 is responsible for the communication between the hard disk host (HOST) and the storage device, where the storage device is realized by several FLASH memory card circuits 2 . One end of the FLASH hard disk controller 1 is connected to the FLASH memory card circuit 2 through a memory card interface, and the other end is connected to the hard disk host (HOST) through a standard hard disk interface such as IDA (ATA), SATA interface or USB interface.

[0026] According to FIG. 2 , the FLASH hard disk controller 1 is composed of a hard disk interface module 11 , a data buffer 12 , a logic circuit 13 , a CPU 14 and a control interface module 15 . The controller interface 15 can be any one of SD, MMC, MS, or a custom protocol interface, and is not limited thereto. The control interfa...

Abstract

The invention discloses a hard disk based on a plurality of FLASH memory cards, which has the advantages of small volume, light weight, power saving, low calorific power and no running noise. The hard disk based on the FLASH memory cards comprises a FLASH hard disk controller and a plurality of FLASH memory card circuits. The FLASH hard disk controller comprises a hard disk interface module, a data buffer, a logic circuit, a CPU and a control interface module, wherein the CPU manages the FLASH memory card circuits; each FLASH memory card circuit comprises a FLASH memory card controller and one or a plurality of FLASH memory units; and the FLASH memory card controllers are communicated with the data buffer and the CPU by an SD, an MMC, an MS or any custom interface. The invention can combine the prior hard disk standard, has an interface signal and transmission speed defined by the hard disk standard, can be communicated with a hard disk host by the hard disk standard and can replace the traditional hard disk by good properties.

Description

technical field [0001] The invention relates to the technical field of digital storage, in particular to a hard disk based on multiple FLASH memory cards. Background technique [0002] Hard disk is a non-volatile storage device that can store and access data quickly through magnetic media. The rate is developed from 10Mbps to 150MB / s. Hard disk is an important part of computer. With the development of technology, hard disk is used more and more widely, and can also be used in digital cameras, digital players and digital game consoles. [0003] The traditional hard disk structure is realized by multiple rapidly rotating disks, and data is recorded on the disks. Hard disk platters generally use plastic or glass as the substrate, and then coat a thin layer of magnetic material on the substrate. Currently, the highest single disc capacity has reached 20GB. In the future, the capacity of a single disk of a hard disk will continue to increase, which puts forward higher and hig...
