A memory cell includes a light emitting unit, a phosphorescent layer, a polarization filter and a light detecting unit. The light emitting unit selectively generates a first light signal in response to a write data. The phosphorescent layer generates a second light signal using an energy absorbed from the first light signal. The polarization filter either passes the second light signal to output the passed second light signal as a third light signal or blocks out the second light signal in response to the write data. The light detecting unit generates a read data by detecting the third light signal. |
