Nonvolatile static random access memory cell and memory circuit

A non-volatile static random access memory cell, comprising:

• a static random access circuit, having a first terminal and a second terminal respectively having a first voltage and a second voltage, wherein stored data is determined by the first voltage and the second voltage;
• a first storage device, having a first connection terminal and a second connection terminal, wherein the first connection terminal of the first storage device is coupled to the first terminal of the static random access circuit;
• a second storage device, having a first connection terminal and a second connection terminal, wherein the first connection terminal of the second storage device is coupled to the second terminal of the static random access circuit;
• and
• a switch unit, respectively coupled to the second connection terminal of the first storage device and the second connection terminal of the second storage device, wherein the switch unit is turned on/off in response to a switching signal, and when the switch unit is turned on, the two second connection terminals are directly conducted to a bit line or a complementary bit line corresponding to the bit line by the switching unit, wherein the switching signal is different from a word line signal.
