| 摘要 |
The present disclosure relates to a semiconductor memory device and a method of operation the semiconductor memory device, which sets an encoding value by sequentially defining ranges used for recognizing distribution of memory cells based on a middle range and then performing a read operation in an order from the middle ranges to an outermost range, thereby capable of using infinite ranges for recognizing the distribution of the memory cells without addition of a circuit to an inside of the semiconductor memory device. |
