Abstract
Description
technical field
[0001] The invention belongs to the technical field of storage, and in particular relates to an SSD solid state disk with a multi-channel fully interconnected architecture and a control method thereof. Background technique
[0002] In order to meet the large-capacity and high-performance storage requirements of big data and cloud storage systems, SSD (Solid-State Drive) solid-state disks based on NAND flash have become commonly used storage media in mainstream storage systems. SSD is mainly composed of flash media and flash controller. Generally speaking, the flash controller has a structure based on an ARM processor, and the ARM processor is connected to a multi-channel NAND flash controller and a SATA / PCI-e controller through an AHB bus matrix. , The AHB bus matrix is also connected with peripheral equipment, SDRAM controller, DMA controller, SRAM and ROM, etc.
[0003] The connection mode of SSD internal channels and chips has undergone a transformation...
