Abstract: A first read operation is performed using a first voltage level to read data from a memory array. An instant bit count corresponding to a number of bits in the data read from the memory array is determined. A recorded bit count corresponding to a number of bits in the data that was written at a time of writing the data to the memory array is accessed. A difference between the instant bit count and the recorded bit count is obtained. Conditioned on determining that the difference is less than or equal to a first threshold value, the data read from the memory array is output using the first read operation. Conditioned on determining that the difference is greater than the first threshold value, a second read operation is performed using a second voltage level that is distinct from the first voltage level.

Abstract: A method for programming a non-volatile memory including a plurality of blocks, each block including a plurality of sections, each section including at least one page, and each page including a plurality of memory cells. The method includes checking a current section of the plurality of sections against a damaged section table to determine whether the current section is damaged. The damaged section table records information about whether a section in the memory is good or damaged. The method further includes using the current section for programming if the current section is not damaged.

Abstract: A method for managing memory includes setting a state of a first memory cell to a first state representing a first data and setting a state of a second memory cell to a second state representing the first data. If the state of the second memory cell has changed to a third state representing a second data different from the first data, the method also includes changing the state of the second memory cell back to the second state.

Abstract: A method for reading data from memory cells of a target word line in a semiconductor memory includes determining a disturbance status of the target word line. The disturbance status reflects a disturbance of a neighboring word line on the memory cells of the target word line. The method further includes determining a read voltage for the target word line according to the disturbance status of the target word line and applying the read voltage to the memory cells of the target word line.
