Abstract
A method of reducing coupling effect in a flash memory is disclosed. A neighboring page is read, and a flag is set active if the neighboring page is an interfering page. Data are read from the neighboring page at least two more times using at least two distinct read voltages respectively. The threshold-voltage distributions associated with an original page and the neighboring page are transferred according to the read data and the flag.
