Embodiment Construction

[0029] like figure 1 , 2 As shown, a FLASH-based hard disk is compatible with existing hard disk specifications, and has interface signals and transmission speeds defined by hard disk specifications, including:

[0030] The FLASH storage device 3 is formed by cascade connection of several FLASH memories 31 for storing data;

[0031] FLASH hard disk controller 2 is made up of interface circuit module 21, data register 22, CPU23 and some FLASH controller modules 24, and each FLASH controller module 24 one ends correspond to a FLASH memory 31 connected with FLASH storage device 3, The other end is connected to the data buffer 22 and the CPU 23 in parallel, controls the data exchange between the FLASH storage device 3 and the corresponding host, manages the FLASH storage device 3 to complete correct data storage or access, and each FLASH controller module 24 coordinates with the CPU 23 Work in parallel, so that these FLASH controller modules can simultaneously read and write a p...

Abstract

The invention discloses a FLASH-based hard disk with small volume, light weight, low power consumption, low calorific value, no running noise and strong shock resistance, including a FLASH storage device, a FLASH hard disk controller and a hard disk interface unit, and a FLASH hard disk The controller is composed of an interface circuit module, a data buffer, a CPU, and several FLASH controller modules. One end of each FLASH controller module corresponds to a FLASH memory connected to the FLASH storage device, and the other end is connected in parallel to the data buffer and CPU. The present invention replaces the magnetic media used in traditional hard disks with small-sized and light-weight FLASH, and at the same time completely abolishes the heavy mechanical structure of traditional hard disks, reduces operating power consumption and calorific value, eliminates mechanical noise, and at the same time achieves traditional The reading and writing speed and performance of the hard disk, and the interface of the traditional hard disk is maintained, and it has good system compatibility.

Description

technical field [0001] The invention relates to a data storage device, in particular to a hard disk based on FLASH. Background technique [0002] As an important part of the computer, the hard disk has undergone continuous innovation and improvement since its birth, and its technology and performance have been very mature and perfect. [0003] The traditional hard disk is composed of hard disk assembly (HDA for short), the core is packaged in the purification chamber of the hard disk, including floating magnetic head assembly, magnetic head driving mechanism, disk and spindle driving mechanism, front read and write control circuit, etc. . Among them, magnetic heads, motors, platters and interfaces play an important role in the upgrading of hard disk technology: [0004] The magnetic head technology is one of the important technologies for the upgrading of the hard disk technology. The single disk capacity of the current hard disk is generally above 10GB, and the highest si...
