Abstract
A memory device and a method for operating the memory device are provided. The memory device includes a memory cell and a bit line connected to the memory cell. A negative voltage generator is connected to the bit line. The negative voltage generator, when enabled, is operative to provide a first write path for the bit line. A control circuit is connected to the negative voltage generator and the bit line. The control circuit is operative to provide a second write path for the bit line when the negative voltage generator is not enabled.
