near field communication system

By introducing capacitors and independent power supply areas into the near field communication system, it is ensured that data can still be saved when the power is turned off, which solves the problems of large size and high cost of non-volatile memory in the existing technology, and uses volatile memory to achieve more efficient operation. The small storage device and standard process requirements provide an efficient data storage solution.

AI Technical Summary

Problems solved by technology

However, non-volatile memory has disadvantages such as large size and high price
Electrically Erasable Programmable Read-Only Memory is usually much larger in size than general volatile memory, and its data density is also very low
In addition, flash memory requires additional masks and special processes, which are also expensive
Today, in advanced processes (for example: 40nm, 65nm process), there is still no mature non-volatile memory solution, so the development of near field communication systems in advanced processes has encountered many problems

Embodiment Construction

[0013] Certain terms are used in the description and claims to refer to particular elements. 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" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

A near field communication system includes a power supply device, a capacitor, a near field communication controller, and a storage device. The capacitor is charged by the power supply device; the near field communication controller includes an independent power supply area, and the power supply device and / or the capacitor supplies power to the independent power supply area of ​​the near field communication controller; the storage device is arranged in the independent power supply area, to save data. When the power supply device is removed or turned off, power is supplied to the independent power supply area by a capacitor. The above-mentioned near field communication system can still save the data in the storage device and perform normal access operations when the power device is removed or turned off.

Description

technical field [0001] The present invention relates to a near field communication (Near Field Communication, NFC) system, and more particularly to a near field communication system including a storage device, wherein the near field communication system can still operate normally even when the power device is removed or turned off . Background technique [0002] In the near field communication system, the near field communication controller can be used as an electronic card (for example: the emulation card mode CardEmulationMode specified by NFCForum), which has a variety of applications, such as: mass rapid transit (Metropassing), banks, etc. NFC controllers generally require non-volatile memory (Non-VolatileMemory, NVM) to store important data, so that even when the power device of the NFC system is removed or turned off, data access can still be performed normally. [0003] Generally speaking, non-volatile memory often uses Electrically Erasable Programmable Read-Only Me...
