Abstract: A data outputting method of a memory circuit is illustrated. The memory circuit having at least 16 data buffers DQ[0]˜DQ[15] for storing at least 16 batches of data is provided. If a quadruple data outputting mode is selected for the memory circuit, when the clock signal triggers the 16 data buffers DQ[0]˜DQ[15], the 4 batches of the data stored in the 4 data buffers DQ[0], DQ[1], DQ[8], DQ[9] via 4 input/output pins connected to the 4 data buffers DQ[0], DQ[1], DQ[8], DQ[9], the batch of data stored in the data buffer DQ[2n+2] is transferred to be stored in the data buffer DQ[2n], and the batch of the data stored in the data buffer DQ[2n+3] is transferred to be stored in the data buffer DQ[2n+1], for n is an integer from 0 through 2, and from 4 through 6.

Abstract: A method for conducting an over-erase correction describes the steps of: conducting a first erase and verification operation; using an FN soft program to correct over-erased cells if bit line leakage is found after the first erase and verification operation; conducting a second erase and verification operation; and using a hot carrier HC soft program to correct over-erased cells if bit line leakage is found after the second erase and verification operation.
