Assignee: SK HYNIX INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A memory device, comprising:
a memory structure including at least one non-volatile memory cell capable of storing multi-bit data; and
a control device configured to:
perform a program verification after a first program pulse is applied to the at least one non-volatile memory cell,
determine a program mode for the at least one non-volatile memory cell based on a result of the program verification, and
change a level of a pass voltage, which is applied to another non-volatile memory cell coupled to the at least one non-volatile memory cell, from a first level to a second level which is higher than the first level or a setup time for changing a potential of a bit line coupled to the at least one non-volatile memory cell, according to the program mode,
wherein the performing, the determining and the changing are performed during a data program operation of applying a plurality of program pulses to program multi-bit data to the at least one non-volatile memory cell.
