Embodiment Construction

[0057] Generally speaking, a storage device includes a rewritable non-volatile memory module (rewritable non-volatile memory module) and a storage device controller (also referred to as a storage controller or a storage control circuit). Generally, the storage device is used together with the host system, so that the host system can perform data transmission operations on the storage device. For example, writing data to or reading data from a storage device.

[0058] figure 1 It is a schematic block diagram of a host system and a storage device according to an embodiment of the present invention.

[0059] Please refer to figure 1 , the host system (Host System) 10 includes a processor (Processor) 110 , a host memory (Host Memory) 120 and a data transfer interface circuit (Data Transfer Interface Circuit) 130 . In this embodiment, the data transmission interface circuit 130 is electrically connected (also referred to as electrically connected) to the processor 110 and the ho...

Abstract

The invention provides a data transmission method, a storage controller and a list management circuit. The method comprises the steps of receiving a transmission instruction from a host system, wherein the transmission instruction includes a starting logical block address, the number of logical blocks, first entity region page indexes and second entity region page indexes and is used for instructing target data to be transmitted between at least one target logical block of a reproducible nonvolatile memory module and at least one target memory page of a host memory; if a second memory page address is a first list starting address of a first entity region page index list corresponding to the transmission instruction, caching multiple entries of at least one entity region page index list corresponding to the transmission instruction; transmitting corresponding data according to the cached entries. By means of the technical scheme, the data transmission speed is increased, and the workingefficiency of carrying out data transmission operation with a storage device is improved.

Description

technical field [0001] The present invention relates to a data transmission method, and in particular to a data transmission method and a storage controller and list management circuit using the method. Background technique [0002] The rapid growth of digital cameras, mobile phones, and MP3 players has led to a rapid increase in consumer demand for storage media. Since rewritable non-volatile memory (rewritable non-volatile memory) has the characteristics of data non-volatility, power saving, small size, no mechanical structure, and fast read and write speed, it is most suitable for these electronic products. Therefore, the flash memory industry has become a very popular part of the electronics industry in recent years. For example, an embedded Multi Media Card (eMMC) widely used in mobile electronic devices is a storage device using flash memory as a storage medium. [0003] In order to cooperate with the high write / read speed of rewritable non-volatile memory storage de...
