Abstract

The invention discloses a solid-state memory based on an ultra-wide digital interface. All solid-state memory devices with digital interfaces in the current market are low in transmission rate. A UWDI (ultra-wide digital interface) control module realizes data transmission between a memory device and a host through a UWDI bus. A data distribution module is used for distributing data received by the UWDI control module to a memory medium control module. A solid-state memory medium control module comprises a plurality of solid-state memory medium control channels, wherein each solid-state memory medium control channel corresponds to one solid-state memory medium. A data collection module is used for collecting data flow transmitted by the channels of the solid-state memory medium control module to the UWDI control module. Different from existing standard digital interfaces such as an ATA (advanced technology attachment) and an SCSI (small computer system interface), the UWDI has the advantages of high width, high transmission rate, simple protocol, easiness in implementation and the like.

Description

technical field [0001] The invention belongs to the technical field of data storage, in particular to a solid-state memory based on an ultra-wide digital interface interface. Background technique [0002] With the development of semiconductor technology, solid-state storage devices based on non-volatile storage devices, such as SD cards, MMC cards, and SSDs, have been widely used. At the same time, the market demand for high-speed, large-capacity solid-state storage devices is also growing. Currently on the market, solid-state storage devices using digital interfaces, such as SD cards, MMC cards, CF cards, etc., have low transfer rates, usually within 100MB / s, while solid-state storage devices with higher performance such as SSDs and PCIe solid-state Memory cards use a high-speed serial bus and need to be equipped with a dedicated SATA / PCIe controller before they can be used. At present, there is no high-speed solid-state storage device based on a purely digital bus interf...
