Abstract
A reading device for a memory array is provided. The memory array comprises memory cell columns. The reading device comprises first sensing amplifier groups, a second sensing amplifier group, and an output unit. Each first sensing amplifier groups selectively generates a first sensing output signal. The second sensing amplifier group generates a second sensing output signal. The output unit selectively outputs one of the second sensing output signal and the first sensing output signals according to a page address signal. In a reading operation period, the reading device reads data from a column group to the first sensing amplifier groups. In the reading operation period, when the page address signal indicates an initial input address, initial address data read from the specific column set corresponding to the initial input address among the column group is transmitted to the second sensing amplifier group to generate the second sensing output signal.
