As the physical size of NAND flash cells reduces, more cells are accommodated per unit area, increasing storage capacity. However, this may lead to higher interference with the charge trapped in the cell, resulting in a larger error bit rate. Each cell can hold more bits, which means the buffer between voltage levels decreases and read errors become more likely. Without countermeasures, this leads to failures in modern NAND flashes after a short time. Error correction is therefore one of the most important functions in memory products.
