A memory device includes a memory array, write drivers and a controller. The memory array includes a plurality of memory units respectively arranged in a plurality of bit lines. The write drivers generate a plurality of write bit signals respectively inputted to the bit lines. The controller provides a voltage mode control signal and a current mode control signal. The controller is electrically coupled to the write drivers. Each of the write drivers generates a respective write bit signal of each of the write drivers according to the voltage mode control signal and the current mode control signal. When each of the memory units is in a set state, the controller outputs the voltage mode control signal and the current mode control signal to the write drivers. When each of the memory units is in a reset state, the controller outputs the voltage mode control signal to the write drivers.

Memory device and memory writing method

A memory device includes a memory array, a bit line driving circuit, a word line driving circuit, a read/write circuit, a controller, and a reference driving circuit. The memory array includes several memory units. The bit line driving circuit is configured to interpret a memory bit address and to drive a bit line. The word line driving circuit is configured to interpret a memory word address and to drive a word line. The read/write circuit is configured to read, set, or reset the memory units. The controller is configured to switch the memory array to work in a single memory unit mode or a dual memory unit mode. The reference driving circuit is configured to drive a reference line, wherein the reference line comprises several reference units, and the reference line and the reference units are located in the memory array.
