Classification: CPC G | IPC G

Claim 10:
11. A memory system, comprising:
a memory device comprising plural non-volatile memory cells; and a controller configured to receive a write command and write data from a host, determine a location in which the write data is stored in the memory device, and transfer the write data to the memory device,
wherein:
during a data program operation which includes applying a plurality of program pulses to program the write data to the plural non-volatile memory cells, the memory device is configured to:
determine a program mode causing a change of threshold voltages of the plural non-volatile memory cells, and
change at least one of a level of a first control voltage based on the program mode, the first control voltage to be applied to a drain select line (DSL) coupled to the plural non-volatile memory cells,
wherein the memory device is configured to:
determine the level of the first control voltage in response to a temperature of the memory device, and
determine whether the level of the first control voltage is changed or adjusted in response to a number of program pulses applied to the at least one non-volatile memory cell during the data program operation.
