Embodiment 1

[0061] Such as Figure 7 As shown, this embodiment is a high-reliability PCIe SSD controller module.

[0062] Specifically: the PCIe-to-PATA conversion module and the high-reliability CF card controller are placed on the same PCB board, and the two are connected by the PATA bus.

[0063] The requirements for the PCIe to PATA conversion module, PATA bus, and CF card controller are as follows:

[0064] The PCIe to PATA conversion module has a PCIe interface (i.e. the second interface) and a PATA interface (i.e. the first interface). The PCIe to PATA conversion module converts the reading and writing of the CF card controller on the PCIe interface into the reading and writing on the PATA interface. PCIe to PATA conversion module correspondence Figure 5 The interface conversion module in the module is used to convert the PCIe bus to the PATA bus.

[0065] The PCIe interface of the PCIe-to-PATA conversion module meets at least PCIExpressBaseSpec.Revision1.0a.

[0066] The PATA...

Embodiment 2

[0098] Such as Figure 8 , Figure 9 As shown, it is another SSD controller module that implements a high-reliability Ethernet interface (XAUI, SGMII, etc.).

Abstract

The invention provides a controller module of a solid state disk. The module comprises a memory controller for connecting a NAND FLASH memory, and an interface conversion module connected to the memory controller through a first interface. The interface conversion module is equipped with a second interface; the interface conversion module realizes mutual conversion of the signals of the second interface and the signals of the first interface and is connected to the memory controller through the first interface. The module of the invention can be used as the controller of the solid state disk of a high reliability PCIe interface or the solid state disk of an SGMII interface or XAUI interface.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a controller module of a solid-state hard disk. Background technique [0002] Usually, such as figure 1 As shown, the SSD solid-state hard drive is composed of a controller (FlashMemoryController) and multiple flash memories (NandFlash). Specific examples such as figure 2 As shown, the CF card is composed of a CF card controller and 4 pieces of flash memory. Such as image 3 As shown, the SATA disk is composed of a SATA controller and a flash memory. Such as Figure 4 As shown, SD card consists of SD card controller and flash memory. [0003] Since SSDs with PCIe interfaces do not have high-reliability controllers, high-reliability SSDs with PCIe interfaces cannot be manufactured; although the reliability of CF card controllers is high, it is difficult for the interface of the controller to be used on the PCIe bus. Contents of the invention [0004] The technical problem to ...
