Description

non-volatile digital memory

【Technical field】

The utility model relates to a non-volatile memory storage device, in particular to a non-volatile digital memory paper sheet, or a non-volatile memory storage device packaged in a paper shape.

【Background technique】

The characteristics of non-volatile memory (Non-Volatile Memory; NVM) are: when the current is turned off, the information stored in this memory will not disappear and can still be saved, and it has small size, low power consumption, and is not vulnerable to advantages such as physical damage. At present, non-volatile memory storage devices (Non-Volatile Storage Device) have been widely used in daily life, such as hard disk drives (Hard Disk) in personal computers, compact disks (Compact Disk; CD) used for backup data, or early Magnetic Tape, Flash Memory Card and USB Thumb Disk, which are more popular in consumer electronics in recent years, and Floppy Disk, which were used in the early years, etc. These storage devices can store a large amount of digitized data in a very small physical space in an extremely efficient manner.

Flash memory is currently a non-volatile memory storage medium with the highest "storage/cost" benefit. For example, the well-known Secure Digital Memory Card (SD Card) uses flash memory as its storage medium, which can provide a higher memory capacity and save space for the Secure Digital Memory Card. Please refer to Figs. 1 and 2, the existing secure digital memory card usually includes an upper casing 210, a lower casing 230 and a circuit board 220 packaged between the upper casing 210 and the lower casing 230, wherein the circuit The board 220 includes conductive terminals 221 , a memory control unit 222 and a memory 223 . However, when using a secure digital memory card, users need to use an additional card reader device and driver software to read and write, which makes the cost higher than traditional paper, and cannot have the convenience of direct writing/reading with the naked eye as traditional paper , Naturally, it is also not conducive to manual file organization, so from the perspective of traditional paper recording data, storage and use habits, secure digital memory cards are not an appropriate medium. On the contrary, the number of printed characters on a traditional A4 paper is about 1200 words. Although it can be written immediately, bound into a book and easy to organize files manually, a secure digital memory card with a memory capacity of 2GB can replace about 80,000 A4 papers. , which greatly saves the space occupied by paper and the cost of paper, and the secure digital memory card can rewrite/read data many times, but traditional paper cannot be rewritten, and it also lacks the convenience that digital data can be searched by computer.

Therefore, it is necessary to provide a new storage device that can overcome the shortcomings of existing non-volatile memory storage devices and traditional paper, and at the same time have reusable memory capacity, fast search, and direct writing of traditional paper. The features of naked eye reading and easy manual file arrangement.

【Content of utility model】

The purpose of this utility model is to provide a non-volatile digital memory paper, which has the advantages of both traditional paper and non-volatile digital storage media, and is especially suitable for digital storage that only requires small capacity, low cost of consumables, and can be used for Application of manual archiving.

In order to achieve the aforementioned purpose of the utility model, the utility model provides a non-volatile digital memory sheet, which includes an upper layer of paper, a lower layer of paper and a flexible circuit packaged between the upper layer of paper and the lower layer of paper plate. The flexible circuit board includes a data transmission interface, a non-volatile memory control unit and a non-volatile memory. The upper layer of paper and the lower layer of paper can be glued together to seal the flexible circuit board between the two, wherein the upper layer of paper is provided with an opening to expose the data transmission interface and external electronic devices for data transmission ; The power supply of the utility model is also supplied from the outside through the data transmission interface, and there is no power supply device.

The difference between the non-volatile digital memory paper of the utility model and the traditional paper is that the data can be repeatedly stored, and even if the packaging part of the digital memory paper is damaged, the digital data stored therein can still be taken out. The difference from common memory cards is that the non-volatile digital memory paper of the utility model has the convenience of being able to write directly/read directly with the naked eye, is easy to organize files artificially, and has low cost, and can be used as consumables.

Therefore, compared with the prior art, the non-volatile memory and the non-volatile memory control unit of the utility model are pasted on the flexible circuit board in the form of unpackaged chips, which can save packaging costs and save chip packaging. Space. Because of the adoption of paper encapsulation and flexible circuit board, the utility model can obtain the flexibility and elasticity similar to that of paper, and can write relevant search data or summaries of digital data stored in the paper on the upper and lower layers of paper. , managed manually without the assistance of computer equipment. The non-volatile digital memory paper of the utility model can simultaneously have the characteristics of traditional paper being writable, bound into a book, and easy to be manually sorted and filed, as well as the digital data storage of the non-volatile memory storage device, which can be repeatedly edited by a personal computer, And quickly search data, build retrieval and other functions.
