New description: [New technology field] and especially related to a solid state The present invention relates to a hard disk hard disk. [Prior Art] The development of hard disks today has gradually matured and is widely used in various table-type computers, notebook computers, and computers. However, since the hard disk is a device that operates mechanically, the hard disk is extremely resistant to impact, and it is likely that the data in the storage hard disk is completely destroyed due to the impact. ... In addition, the hard disk is extremely sensitive to shaking, and slight shaking may disturb. The head of the shell is taken. And compared to other forms of disk, the power consumption of the disk is larger and the heat is also an important factor affecting the life of the hard disk read head. There is a need for the development of another storage device, which can be used instead of the harder (A) to perform access operations, and can improve the low stability of the conventional hard disk. [New Content] The present invention provides a solid state hard disk for accelerating access speed by configuring at least two 'flash memories' as a disk array. In one aspect of the present invention, a solid state hard disk is provided, comprising: a flash memory, a second flash memory and an access control unit. The access control feature of the first-memory body is different from that of the second flash memory, and the access control I^ can configure the first flash memory and the second flash memory as a disk array (RedUndant Array 〇 f Independent Disks; RAID).

That is, the second/second second controller 123 can directly manage the access operation of the first-flash memory 17 J-flash memory 18 to improve the access efficiency of the overall system. ▲ In this embodiment, the _flash is assigned by using the bridge 121. The access operation of the body 17 and the first flash memory 18 can connect the solid state hard material to a different external host using the same communication protocol, and for the different external host, by using the bridge 121 The access operation of the .17 and the second flash memory can increase the multiple flashes of the body. Referring to 帛3®, a functional block of the bridge of FIG. 2 is shown. FIG. 0 The bridge 121 includes a transmission interface 121a for connecting the first controller 122 and the first controller 123. All control signals and data from the bridge 121 can be transmitted to the first controller 122 and the second controller 123 by the transmission interface i2ia. 7 M344552, the bridge 121 provided in this embodiment includes a disk array configuration group 121b, which can configure the first fast integration 18 as a disk array (RAID 〇; ^二二flash memory interface = The real towel 'magnetic material column G configuration module 121 b can improve the access performance by transmitting the rabbit flash memory 17 and the second flash memory 18 to a disk (four) fast wire speed. In addition, the bridge 121 is — & 3 another disk array 1 configuration module 121 c 'which can configure the first flash bridge 1 7 also μ * 』 己 隐 隐 17 and the second flash memory 18 are configured as A disk array 1 (RAm υ. Specifically, the disk array 1 can also be configured to transmit the flash memory 17 and the second flash memory u to be damaged in the flash memory. When the access worker = flash memory is executed, the reliability of the backup and the data mode are improved. The 'bridged stomach 121 can further include a multiple disk configuration based on the data to be stored. The attributes are stored in the younger brother: the flash memory 17 and the second flash memory 18. The multiple magnetic 磾 ^ ^ ^ Zhu configuration 杈 group 121d can be stored according to the first flash δ hexamed body 17 and the second flash sensible data genus (four) stomach material, characteristic storage and storage efficiency and In this embodiment, the first flash 171 ^ ^ ^ K 隐 丨 7 further includes a boot sector. The boot 171 can be configured by the multiple disk configuration module 121d. 0 ^ ^ SLC fAl ^ ^ 17 ^ * SLC ^ ^ | £ ^ 〇 Because ^(4) memory has high read/write times and high (four) degrees, M344552 is quite suitable for storing boot programs, such as operating systems. When enabling multiple disks Configure the core group 121d%. The multi-disk configuration module i2id will judge whether the desired program is stored. If the result is the boot program, the boot program is stored in the boot area of the SLC flash memory. In addition, in this embodiment, the second flash memory 18 further includes a data magnetic area 181. The data magnetic area 181 can also be configured by a multiple disk configuration module.
並且，第二快閃記憶體18可採用一 mlc快閃記憶體。 由於MLC快閃記憶體具有高容量的特性，故相當適合用來 儲存檔案資料，例如影像檔、聲音檔或文件檔等。當致能 多重磁碟配置模組121(1時，多重磁碟配置模組12id將判 斷所欲儲存的資料是否為開機程式？若判斷的結果為非開 機程式時，則將所述資料儲存在MLC快閃記憶體的資料磁 區中。 由上述說明可知，前述實施例之固態硬碟可將多重快 閃記憶體配置為一磁碟陣列，以便加快存取速度或增進數 據安全。另一方面，可依據不同快閃記憶體的存取^性而 將具有不同屬性的資料存放於對應的快閃記憶體中，以提 高系統之儲存管理效率。 雖然本新型已以一實施例揭露如上，然其並非用以限 定本新型，任何熟習此技藝者，在不脫離本新型之精神和 範圍内，當可作各種之更動與潤飾，因此本新型之保護範 圍當視後附之申請專利範圍所界定者為準。 【圖式簡單說明】 M344552 為讓本新型之上述和其他目的、特徵、優點與實施例 能更明顯易懂，所附圖式之詳細說明如下： 第1圖繪示依照本新型一實施例的固態硬碟之一種功 能方塊圖。 第2圖繪示第1圖之固態硬碟的存取控制器之一種功 能方塊圖。Moreover, the second flash memory 18 can employ a mlc flash memory. Because MLC flash memory has high capacity, it is quite suitable for storing files such as image files, sound files or file files. When the multiple disk configuration module 121 is enabled (1, the multiple disk configuration module 12id will determine whether the data to be stored is a boot program? If the result of the determination is a non-boot program, the data is stored in In the data area of the MLC flash memory, it can be seen from the above description that the solid state hard disk of the foregoing embodiment can configure multiple flash memories as a disk array to speed up access or improve data security. According to the accessibility of different flash memories, data with different attributes can be stored in the corresponding flash memory to improve the storage management efficiency of the system. Although the present invention has been disclosed as an embodiment above, It is not intended to limit the present invention, and any person skilled in the art can make various changes and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the scope of the appended patent application.
