An image forming apparatus and a method of controlling the same which may prevent brokenness of data displayed on a display are provided. The image forming apparatus performs a read operation on data previously stored at a specific address of a storage unit of an LCD module or on data stored through a write operation. The image forming apparatus compares data acquired through the read operation and known data. If the data acquired through the read operation and the known data are different, the image forming apparatus adjusts a setup time of an enable signal to prevent brokenness of data due to incorrect timing of the enable signal.

A method of estimating a read level for a memory device includes calculating first information corresponding to at least one among information about the number of cells having a particular logic level in data to be programmed and information about the number of cells having a particular cell state and storing the first information during a program operation; reading the data based on a threshold level that has been set and calculating second information about the number of cells in at least one state defined by the threshold level with respect to the read data; calculating third information about the number of cells in the at least one state, which corresponds to the second information, using a probability based on the first information; comparing the second information with the third information; and determining whether to change the threshold level according to the comparison result.
