Abstract
A memory device and a control method of the memory device are provided. The memory device includes a decoding circuit, Q switching circuits and Q blocks. The decoding circuit generates Q select signals. A k-th select signal of the Q select signals has a first select voltage. The other (Q−1) select signals have a second select voltage. The Q switching circuits receive an erase voltage, and generate Q common source line signals according to the Q select signals. A k-th common source line signal of the Q common source line signals generated by a k-th switching circuit of the Q switching circuits has the erase voltage. The Q blocks receive the Q common source line signals, respectively. A k-th block of the Q blocks is erased according to the k-th common source line signal.
