Memory: JS28F256P30B95A Application Field and Working Principle

JS28F256P30B95A is a type of memory product produced by the American semiconductor company Intel. It is a one-time programmable non-volatile Flash memory chip. This chip is mostly used to store critical boot code and other firmware such as BIOS in portable computer or embedded products. It also supports rewritable up to 100,000 write/erase cycles. This article will describe the application field and working principle of JS28F256P30B95A.

Application Field

JS28F256P30B95A is mainly used in portable computers, embedded systems, consumer electronics and telecommunications applications, such as mobile phones, digital cameras, security systems and so on, which require non-volatile memory that can be programmed once and then retained without external power, ensuring information security and reliability. In addition, this type of flash memory chip is also widely used as program storage device in industrial, automotive and other embedded applications.

The JS28F256P30B95A is able to store up to 256 megabytes (MB) of data and instructions. Its wide voltage range enables it to be operated in a variety of environments. It also has on-chip voltage conversion and ECC (Error Correction Code) to ensure reliable operation. Of the 10 output modules available, 4 are suitable for high speed data transmission. The chip can also be connected with other external systems and is highly compatible.

Working Principle

The working principle of JS28F256P30B95A is the same as that of other Flash memory chips. It uses electrons to store data and instructions in a non-volatile manner. The chip can be programmed and erased multiple times and has a long storage life of 10 years or more. Each bit cell contains one transistor and one floating-gate structure. The transistor acts as a switch and the floating-gate structure stores electrons.

In order to store data or instructions, electrons are injected into the floating-gate structure by applying a suitable voltage and current to the bit cell. When electrons are injected, a voltage potential is created, which can be sensed and read by the chip. By varying the voltage and current, it is possible to write one or zero in the bit cell. In order to erase the information, a higher voltage and current are applied to the bit cell, which causes electrons to be drawn from the floating-gate structure, thereby restoring it to its original state.

Conclusion

JS28F256P30B95A is a type of memory product produced by Intel. It is a one-time programmable non-volatile Flash memory chip and is mainly used in portable computers, embedded systems and telecommunications applications. The chip can store up to 256 megabytes of data and instructions and is also highly compatible with other external systems. The working principle of the chip is to store data or instructions by injecting electrons into the floating-gate structure of the bit cell.
