Abstract

The invention relates to a device with storage function, comprising: a first storage area suitable for storing general data; a second storage area suitable for storing label data; a contact interface suitable for interacting with external devices; a non-contact The interface is suitable for interacting with external devices; the system configuration area is suitable for storing system configuration data, and the system configuration data includes the setting information of the storage area access mode; the processor is suitable for receiving external device, according to the storage area access mode setting information to control the contact interface to access the first storage area or the second storage area; it is also suitable for when the non-contact interface receives an instruction from an external device and controlling the contactless interface to access the first storage area or the second storage area according to the type of the instruction. The invention can simultaneously access data in different data formats stored in the device.

Description

technical field [0001] The invention relates to the communication field, in particular to a device with storage function. Background technique [0002] Devices with memory functions include memory and its main controller. Traditional memories include: [0003] Static Random Access Memory (SRAM); [0004] Dynamic Random Access Memory (DRAM); [0005] Electrically Erasable Programmable Read Only Memory (EEPROM); and, [0006] Non-volatile flash memory (for example, NOR Flash and NAND Flash). [0007] These memories use different memory technologies and have different bus interfaces and memory characteristics. However, their common feature is that they are connected to the main controller through a direct electrical interface, that is, a contact interface, and read or store data through the contact interface. [0008] With the development of radio frequency identification technology (Radio Frequency Identification, RFID), the use of LF, HF, UHF and other different radio fr...
