Working Principles

The JS28F256P33BFA utilizes a parallel interface to communicate with the host device. It stores data using floating-gate transistors that can retain charge even when power is removed. When reading data, the stored charge is measured, and when writing data, the charge is adjusted accordingly. The memory cells are organized into blocks, allowing for efficient program and erase operations.
