Abstract
The present invention relates to enhancing low power consumption of a display device having a SRAM. The display device includes a drive circuit receiving video data; video lines connected the drive circuit; and pixels connected to the video signals. The drive circuit includes a memory storing the video data in memory cells. Each memory cell includes a first inverter with input and output terminals connected to first and second nodes, respectively. A second inverter has output and input terminals connected to the first and second nodes, respectively. A First and second transistors between a first data line and the first node each have a control terminal connected to a first word line or a third word line, respectively. Third and fourth transistors between a second data line and the second node each have a control terminal connected to a second word line or a fourth word line, respectively.
