A stereoscopic image display device includes a display panel and an optical lens assembly. The display panel includes a plurality of pixels. The display panel temporally divides M view images corresponding to M viewing spaces to display the temporally divided image on a display panel. ‘M’ is a natural number of no less than two. The optical lens assembly converts the view image displayed on the display panel into N stereoscopic images in which directions of the view images are different from each other to emit the converted view image toward a viewing space corresponding to the view image displayed on the display panel. ‘N’ is a natural number no less than two.

A stereoscopic image display device includes a display panel, a temporal division plate and a lenticular lens. The display panel includes a gate line, a data line, and a unit pixel of a horizontal pixel structure in which a long side is parallel with the first direction and a short side is parallel with the second direction. The display panel displays a 2D image based on an image control signal. The temporal division plate includes a plurality of shutters disposed on the display panel extending in the second direction. The temporal division plate opens and closes m shutters corresponding to each unit pixel, in a sequence, ‘m’ being a natural number no less than 2). The lenticular lens is disposed on the temporal division plate to convert the 2D image passing the temporal division plate into a 3D image.

A hybrid memory device is provided. The hybrid memory device includes a DRAM, a non-volatile memory and a control circuit. The control circuit selects one of output data of the DRAM and output data of the non-volatile memory according to a mode selecting signal and output the selected data. The control circuit outputs data requested to be output from the DRAM when the data requested to be output is in the DRAM, and may output the data requested to be output from the non-volatile memory when the data requested to be output is in the non-volatile memory. Accordingly, the hybrid memory device has a high speed in a read and write operation, and has low power consumption.
