Classification: CPC G | IPC G

Claim 11:
12. A memory device, comprising:
a plurality of memory cells included in a selected page;
a control logic circuit configured to determine a program speed at a time at which memory cells selected from among the plurality of memory cells are programmed to a reference state, among different target program states, while the plurality of memory cells are being programmed to the different target program states, and to change a condition for a program operation based on the determined program speed; and
a voltage generator configured to output program voltages so that remaining program operations are performed under control of the control logic circuit,
wherein the control logic circuit is configured to control a condition of at least one of a level of each program voltage, a level of a step voltage, an active time during which the program voltage is applied to a word line, an offset for the program voltage, and a verify voltage depending on the program speed of the memory cells programmed to the reference state during the program operation, and to generate and output an operation code to which the controlled condition is applied during the remaining program operations.
