Memory: JS28F256M29EWHD Application Field and Working Principle

JS28F256M29EWHD is a Flash memory architecture designed for high-volume consumer embedded applications and industrial applications. This Flash device, which has been designed for applications supporting low-power voltage and mixed-voltage operation, is based on a Multi-Time Program/Erase (MTPE) architecture that supports single bits, bytes, or words of data.

Application Field

JS28F256M29EWHD Memory can be applied in different types of embedded and industrial applications, including mobile phones, radio frequency identification tags (RFID tags), television set-top boxes, optical storage media, digital camcorders, automotive applications, and industrial telecommunication applications. The architecture is especially suitable for applications that require low-power operation and portability. With on-chip programmable voltage, this device can be easily configured to work in both high-voltage and low-voltage operation.

Working Principle

The JS28F256M29EWHD Memory is organized into blocks, with each block containing a program page and an erase page. Data is written to the program page, and erased from the erase page. The data is stored on a 2-level MTPE (Multi-Time Program/Erase) scheme, which allows single bits, bytes or words of data to be written, or erased, in a single write cycle. The data is organized into a 6-level write/erase process, with each level of data being written and erased in a single write cycle.

The device employs a 3-level ECC (Error Correction Code) system, with each level of data requiring a specific ECC correction. This ensures that the data written is as accurate and error-free as possible. Additionally, the device utilizes a built-in verification program, which allows the data written to be verified prior to being committed to the memory block.

The JS28F256M29EWHD Memory can be configured for a range of operations and functions, including program page size, ECC level, page replacement, read page size, write page size, and write page offset. The device has been designed to provide a low-power, high-performance solution for consumer and industrial applications requiring low-power operation and portability.
