An integrated circuit device has a display memory which stores data for at
least one frame displayed in a display panel which has a plurality of
scan lines and a plurality of data lines. The display memory includes a
plurality of RAM blocks, each of the RAM blocks including a plurality of
wordlines WL, a plurality of bitlines BL, a plurality of memory cells MC,
and a data read control circuit. Each of the RAM blocks is disposed along
a first direction X in which the bitlines BL extend. The data read
control circuit controls data reading so that data for pixels
corresponding to the signal lines is read out by N times reading in one
horizontal scan period 1H of the display panel (N is an integer larger
than 1).
