Problems solved by technology

[0004] However, the memory cards in the prior art are all used as terminal storage nodes. When bus cascading is realized by setting storage channels, this increases the complexity of the circuit structure to a certain extent.

Embodiment Construction

[0037] The technical solutions provided by the present invention will be further described below in conjunction with the accompanying drawings.

[0038] see Figure 10 , which shows a control method of a storage device in the present invention. A first interface and a second interface are set in the storage device and cascading expansion is realized through the bus on the two interfaces, and a cascading control algorithm is executed in it, which specifically includes the following step:

[0039] Step S1: monitor and obtain data information on the bus;

[0040] Step S2: judging whether the data information is a storage task of the storage device, if the storage device executes the storage task, otherwise the storage task is forwarded through the bus.

[0041] As a preferred technical solution, in the step S2, when sending data through the bus, the storage device actively sends an instruction to seize control of the bus and implement chip selection through the instruction.

Abstract

The invention discloses a control method of a storage device. The storage device is provided with a first interface and a second interface, and cascade expansion is realized on the two interfaces through a bus, and the following steps are executed in the storage device: S1, monitoring and acquiring data information on the bus; and S2, judging whether the data information is a storage task of the storage device or not, if so, executing the storage task by the storage device, and otherwise, forwarding the storage task through a bus. By adopting the technical scheme of the invention, the cascadecontrol algorithm is built in the storage device, so that cascade can be realized through a standard interface, and the storage capacity can be infinitely expanded theoretically to meet the requirements of various applications; and meanwhile, standard interface cascading is adopted, so that the complexity of circuit implementation is further reduced.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a method for controlling a storage device. Background technique [0002] Storage devices are currently commonly used data storage devices. With the advent of the era of big data, the demand for storage capacity is also increasing. In the prior art, storage devices are usually packaged in the form of SSD, MMC card, SD card, eMMC chip, Flash chip, etc. Due to the physical characteristics of NAND Flash itself, direct architecture for large-capacity storage will result in an increase in the chip area of ​​the Flash controller, which greatly increases the technical difficulty and hardware cost of the controller implementation. [0003] On the other hand, with the continuous maturity of memory card technology, memory cards such as SD cards, MMC cards or eMMC chips have been widely used in various storage devices, especially with the wide application of eMMC chips in mobile phone...
