Abstract

A memory device, including a plurality of planes, includes a mode setting component to set an operation mode of the memory device as a verify pass mode to allow a verify operation, performed in the plurality of planes, to forcibly pass; and a verify signal generator for outputting a verify pass signal signaling that the verify operation has passed for each of the plurality of planes.

Claims (21)

1. A memory device, including a plurality of planes, the memory device comprising:

a mode setting component configured to set an operation mode of the memory device as a verify pass mode to allow a program verify operation, performed in the plurality of planes, to forcibly pass; and

a program verify signal generator configured to output a program verify pass signal signaling that the program verify operation has passed for each of the plurality of planes,

wherein the mode setting component outputs verify pass setting information allowing the program verify pass signal to be output for planes performing the program verify operation among any planes with already passing the program verify operation.

2. The memory device of claim 1 , wherein the mode setting component:

sets a loop number for each of the plurality of planes, representing a number of loops required to output the program verify pass signal; or

outputs verify pass setting information that allows the program verify pass signal to be output for each of the plurality of planes.

3. The memory device of claim 1 , wherein the mode setting component sets a program loop number for each of the plurality of planes, representing a number of loops required to output the program verify pass signal.

4. The memory device of claim 3 , wherein the program verify signal generator counts a number of program loops preformed on each of the plurality of planes.

5. The memory device of claim 4 , wherein the program verify signal generator outputs the program verify pass signal when the number of program loops, counted by the program verify signal generator, and the program loop number, set by the mode setting component, are the same for a given plane among the plurality of planes.

6. The memory device of claim 1 , wherein the program verify signal generator is configured to output a program verify fail signal signaling that the program verify operation has failed for each of the plurality of planes,

wherein the mode setting component outputs program verify fail setting information that allows the program verify fail signal to be output for each of the plurality of planes.

7. The memory device of claim 6 , wherein, when the program verify signal generator receives the program verify fail setting information, the program verify signal generator outputs a program verify fail signal of a program loop being performed in a plane corresponding to the program verify fail setting information among the plurality of planes.

8. A method for operating a memory device, including a plurality of planes, the method comprising:

setting an operation mode of the memory device to allow a program verify operation, performed in the plurality of planes, to forcibly pass; and

outputting a program verify pass signal signaling that the program verify operation has passed for each of the plurality of planes,

wherein, the program verify pass signal indicates that the program verify operation has passed for each of the plurality of planes.

9. The method of claim 8 , further comprising:

setting a program loop number for each of the plurality of planes, representing a number of loops required to output the program verify pass signal; and

counting a number of program loops preformed on each of the plurality of planes,

wherein, in the outputting of the program verify pass signal, a signal is output when the counted number of program loops and the set program loop number are the same for a given plane among the plurality of planes.
