Problems solved by technology

Therefore, some information (such as addresses, instructions, previously read data, etc.) is not reused due to increased waiting cycles and repeated transmission, especially in conditions where accesses are performed by frequently switching between different data streams , it is possible to waste a lot of time and access resources

Embodiment Construction

[0020]Certain terms are used in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" and "comprises" mentioned throughout the description and claims are open-ended terms, so they should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" includes any direct and indirect electrical connection means. Therefore, if it is described in the text that a first device is coupled to a second device, it means that the first device may be directl...

Abstract

The invention provides at least a serial peripheral interface controller, a serial peripheral interface flash memory, an access method and an access control method. The access method is used for the serial peripheral interface flash memory. The serial peripheral interface flash memory comprises a flash memory array and supports a plurality of data flows. The access method comprises: a flow starting instruction is received for the data flows of the plurality of data flows, and the flow starting instruction comprises access type and an identification code of the data flow; address information is received, the address information comprises the page address of the page of the flash memory array and an address pointer; data is read from the flash memory array to a flow register corresponding to the data flow according to the flow starting instrument and the page address, or according to the flow starting instrument, the data to be written into the flash memory array us stored into the flow register corresponding to the data flow. High-efficiency operation for data flow storage can be achieved and processing time can be shortened.

Description

technical field [0001] The present invention relates to a memory device, in particular to a serial flash memory device. Background technique [0002] Flash memory devices are commonly used in electronic applications such as personal computers, personal digital assistants (PDAs), digital cameras, and mobile phones. Generally, flash memory devices are classified into parallel flash memory devices and serial flash memory devices. Compared with parallel flash memory, serial flash memory has fewer transmission lines and pins. Therefore, the package size of the serial flash memory can be relatively reduced, and the serial flash memory can be used as the dominant memory of the portable electronic device. [0003] A traditional 8-pin (8-pin) serial peripheral interface (Serial Peripheral Interface, SPI) NAND flash memory includes chip select pin CS#, serial clock pin SCK, serial data input / serial data input and Output pin SI / SO0, serial data output / serial data input and output pi...
