Solid state disk control device and method

Abstract

The invention discloses a solid-state hard disk control device and a control method. The control device includes: a multi-interface compatible physical layer circuit, which is used to generate a physical layer output signal according to the serial / deserialization receiving signal; an input-output circuit, which is used to generate a physical layer output signal according to at least one The signal change of the terminal generates at least one terminal output signal; and the processing circuit is used to make the operation mode of the solid-state hard disk control device suitable for multiple interface types according to the physical layer output signal and / or the at least one terminal output signal one.

Description

technical field [0001] The invention relates to interface detection technology, in particular to a solid-state hard disk control device and method capable of detecting interface types. Background technique [0002] The traditional SSD interface is a Serial Advanced Technology Attachment (SATA) interface. However, since the transmission speed of the SATA interface is gradually unable to meet the demand for high-speed transmission, some solid-state hard disks use the Peripheral Component Interconnect Express (PCI-Express) interface instead. [0003] In order to increase compatibility, some solid-state drives can support SATA interface and PCI-Express interface. This kind of solid-state drive will set the voltage level of a specific pin, so that a host can detect the level of the pin to assign the configuration of the port connected to the solid state drive (Configuration), however, after the host completes the configuration of the port, if the operating mode of the solid stat...

Problems solved by technology

However, because the transmission speed of the SATA interface is gradually unable to meet the needs of high-speed transmission, some solid-state hard disks use the Peripheral Component Interconnect Express (PCI-Express) interface instead.

[0003] In order to increase compatibility, some solid-state drives can support SATA interface and PCI-Express interface. This kind of solid-state drive will set the voltage level of a specific pin, so that a host can detect the level of the pin to assign the configuration of the port connected to the solid state drive (Configuration), however, after the host completes the configuration of the port, if the operating mode of the solid state drive is changed from the first mode (such as SATA mode) to the second mode (such as PCI-Express mode) or another solid-state drive only supports the second mode, and the host will not change the configuration accordingly, so that the solid-state drive or the other solid-state drive cannot be connected to the host normally

Another situation is that the above-mentioned solid-state hard disk operates in a default mode (such as the aforementioned first or second mode) by setting the level of the pin, but a host connected to the solid-state hard disk does not have the ability to detect the pin. Bit function, and the host configures the port connected to the solid-state drive to be incompatible with the preset mode, so the solid-state drive cannot be connected to the host normally
