Memory - 71256SA20YG8 Application Field and Working Principle

Memory technology is an important component of modern integrated circuits, and as the development of electronics technology, has become an indispensable part of our life. Among them, memory such as 71256SA20YG8 is widely used in the fields of communication and computer technology. This paper discusses the application field and working principle of 71256SA20YG8 memory.

Application Field of 71256SA20YG8 Memory

71256SA20YG8 memory is a synchronous static random access memory (SRAM). SRAM is a kind of static random access memory that can maintain the information in the memory without being refreshed, and can be read or written quickly. Its states are usually stored in a four-Transistor structure in a cell, so it can provide long-term memory security, and because it mainly uses SRAM cells, it has a relatively large capacity. Compared with dynamic RAM, it has strong anti-radiation ability, reliable working chip and does not need to refresh, so it is widely used.

The 71256SA20YG8 memory has a capacity of 8KB, which is mainly used in embedded system, sim card, base station, PC and other fields which need fast information access and read and write process. In embedded systems, it can provide a vast space for data storage, such as scientific research, industrial control, network communication and broadcasting, etc.

The 71256SA20YG8 memory can also provide important assistant work for memory simulation and system simulation. Such applications often require high computing speed, high memory capacity and stability of memory in demanding environments, and the 71256SA20YG8 memory provides all of these advantages.

Working Principle Of 71256SA20YG8 Memory

71256SA20YG8 Memory uses flip-flop structure as unit. Flip-flop consists of a pair of cross-coupled inverters, and the flip-flop structure can store data. By providing a cold start circuit, it can store data in the flip-flop structure and transfer data from one flip-flop unit to another. When the reset signal is low level, the flip-flop is reset and the data in the flip-flop is cleared. In this way, the data in the flip-flop can be read, written and cleared.

71256SA20YG8 Memory uses the non-inverted output of the flip-flop structure as the data output line. When the data needs to be written, the data is placed on the data input line at the rising edge of the write pulse, and then the data is stored in the flip-flop structure at the rising edge of the write pulse.

When the data needs to be read, the read pulse is input, and the data stored in the flip-flop structure is output to the data output according to the clock time.

71256SA20YG8 memory is not only widely used in the fields of communications and computer technology, but also has the advantages of high performance, low power consumption, anti-radiation and reliable working chip, and data security without refresh. Its application range is also relatively wide and its working principle is relatively simple.
