JS28F640P33T85A

Memory

JS28F640P33T85A is a high-performance, nonvolatile memory device embedding EEPROM, flash, NAND and NOR applications into one chip. Nonvolatile memories have the capability of holding stored information reliably after power has been removed from the system. This is an essential quality for data that needs to be retained from one system start up to the next and also for information such as system calibration data.

Application Field

The wider range of applications for this device is generally found in automotive, industrial and medical fields which require the incorporation of data that is able to sustain power losses. This device is often used for extended life cycles and for applications that require high speed and reliability.

In the automotive field, the JS28F640P33T85A helps to provide functions such as monitoring of driver and passenger safety equipment, monitoring engine performance and providing tracking of vehicle mileage. In industrial applications, this type of memory is often used to monitor and adjust laser and machine performance, coordinating automation systems and helping to keep track of product progress.

In medical applications, the nonvolatile memory is capable of monitoring conditions such as vital statistics and patient needs while also offering functions such as data storage and backup. This type of application is important for monitoring changes in patient health over time.

Working Principle

The working principle behind the JS28F640P33T85A is based on conventional flash memory technologies, as well as NAND and NOR application programs. In each of these types of memory, transistors are utilized to store data in binary values. In flash memory, these transistors work in a layered pattern in which data is held in memory arrays that can be written or erased on a block-by-block basis.

In NOR flash memory, the data is stored in an array of transistors that can be programmed and erased on an individual bit basis. This means that NOR has the added advantage of being able to store information in a much more efficient and reliable manner. In NAND flash memory, transistors are arranged in a cyclical manner which creates a more efficient way of writing and erasing data.

The advantage of the JS28F640P33T85A includes a combination of these three technologies, creating a single nonvolatile memory device that can store large amounts of data in a small area. Furthermore, this memory has the capability of providing high-performance, low-cost storage in a wide range of applications.
