Abstract
Provided are a non-volatile memory device and a method of programming the same. The method includes: performing a program operation; performing a program verify read operation; and performing a pass/fail determine operation simultaneously with one of a verify recovery operation and a bit line setup operation, after the performing of the program verify read operation.
Claims20
A method of programming a non-volatile memory device, the method comprising:
- performing a program operation;
- performing a program verify read operation;
- and
- performing one of a verify recovery operation and a bit line setup operation simultaneously with a pass/fail determine operation, after the performing of the program verify read operation.

The method of 11, further comprising:
- increasing a program loop counter value if program fail occurs as a result of the pass/fail determine operation;
- and
- repeating the program operation with an increased program voltage.
A non-volatile memory device comprising:
- a memory cell array including memory cells arranged on intersection regions of a plurality of word lines and a plurality of bit lines;
- a row decoder receiving an address to select one word line from among the plurality of word lines;
- a page buffer temporarily storing data bits to be programmed in the memory cell array or temporarily storing data bits detected from the memory cell array through the bit lines;
- a pass/fail check circuit determining whether data values latched in the page buffer are identical to pass data or not during a program verify operation;
- and
- a control logic controlling the row decoder, the page buffer, and the pass/fail check circuit to perform one of a verify recovery operation and a bit line setup operation simultaneously with a pass/fail determine operation, after a verify read operation during a program operation.
