Flash memory apparatus and initialization method for programming operation thereof

A flash memory apparatus, comprising:

• a plurality of memory cells to form a memory cell array;
• a sensing circuit, coupled to the memory cell array;
• and
• a controller, coupled to the sensing circuit and the memory cell array,
• wherein the controller is coupled to a testing apparatus and the testing apparatus performs:
• providing a plurality of programming voltages to perform a plurality of programming actions on the memory cells of the flash memory apparatus, wherein voltage values of the programming voltages are incremental;
• performing a programming verification action on the memory cells by using a programming verification voltage after each time of the programming actions, and recording a current one of voltage values of the programming pulse voltages corresponding to the programming actions with respect to the programming verification actions as a recorded programming voltage value, according to verified results of the programming verification actions;
• providing a plurality of reading pulse voltages after the programming actions to perform a plurality of reading actions on the memory cells, wherein voltages values of the reading pulse voltages are incremental;
• recording a current one of the voltage values of the reading pulse voltages as a recorded reading voltage value, according to reading results of the reading actions;
• and
• obtaining an initial programming voltage according to the recorded programming voltage value, the recorded reading voltage value and a voltage value of the programming verification voltage.
