The working principle of JS28F640J3D75A is very simple. It utilizes a silicon chip as a media, and uses a number of electronic circuits to store and read information. It can be divided into two parts, the logical part and the physical part. The logical part is mainly composed of buffers, address registers, data registers, and control registers. The physical part is composed of transistors and capacitors, and is the structure to store and read data. During the writing process, a circuit is triggered and the transistor is turned on. When the transistor is turned on, the capacitor stored in the chip is charged, and then the data is written. During the reading process, the charge of the capacitor is read and compared with the reference value. If the difference between them is greater than the reference value, it is regarded as 0; if the difference between them is less than the reference value, it is regarded as 1.
In conclusion, JS28F640J3D75A is an advanced non-volatile flash memory with a wide range of applications in data storage, computer, consumer electronics and a variety of peripherals. It works very well in terms of data stability, speed, and power consumption. In the future, this product will be even more widely used in various fields.
