PURPOSE: A non-volatile memory apparatus and an operation method thereof are provided to store five-bit data in a pair of memory cells, thereby improving data storage capacity compared to a two-bit data storage case. CONSTITUTION: A non-volatile memory apparatus includes a memory array(110), operation circuit groups(130,140,150,160,170,180), and a control circuit(120). A memory cell block comprises memory cells connected to word lines. The operation circuit group is comprised in order to perform a read operation or a program operation of the memory cells. The control circuit controls the operation circuit group in order to select a threshold voltage level of a selected memory cell among an elimination level and five program levels according to inputted data.
