Abstract: The disclosure discloses a memory and a method of operating the same. The memory includes an array of memory cells including a plurality of memory cells with a common source, wherein each of the plurality of memory cells with a common source includes two sub-memory cells, each of the sub-memory cells corresponds to a bit line, and the respective bits are electrically independent. Each of the sub-memory cells in the memory according to the disclosure corresponds to a bit line, and the respective bit lines are electrically independent, thereby effectively avoiding interference to other memory cells which will not be programmed during a program operation.
