Abstract

The invention provides a solid-state disk (SSD) control circuit, a related device and a related system. The SSD control circuit comprises: an advanced host controller interface (AHCI) control circuit, which is used to couple a peripheral component interconnect express (PCIe) interface; and a flash memory control circuit, which is coupled to the AHCI control circuit, and is configured to control an access operation of one or more flash memory arrays in the SSD. The AHCI control circuit transmits, to a master device through the PCIe interface, indication information that is used to represent that the AHCI control circuit is coupled to M SSDs, wherein M is a positive integer greater than 1 and less than 32.

Description

technical field [0001] The present invention relates to the technical field of solid-state hard disks, and in particular, to a solid-state hard disk control circuit and a related solid-state hard disk device and a solid-state hard disk access system. Background technique [0002] Most traditional solid state drives (SSDs) are designed to communicate data with a host device through a Serial Advanced Technology Attachment (SATA) interface. However, the transmission bandwidth of the SATA interface is limited. As the access speed of the flash memory chip in the solid-state drive is getting higher and higher, the SATA interface has gradually become a bottleneck for further improving the data transmission speed between the solid-state drive and the host device. SUMMARY OF THE INVENTION [0003] In view of this, how to effectively improve the data transmission speed between the solid state drive and the host device is a problem to be solved in the industry. [0004] This specif...
