Abstract
A nonvolatile memory device comprises a page buffer unit, a counter, a program pulse application number storage unit, and a program start voltage setting unit. The page buffer is configured to output a 1-bit pass signal when a cell programmed to exceed a reference voltage, from among target program cells included in a single page, exists. The counter is configured to count a number of program pulses applied to determine a program pulse application number. The program pulse application number storage unit is configured to store a number of program pulses applied until the 1-bit pass signal is received during a program operation for a first page. The program start voltage setting unit is configured to set a program start voltage for a second page based on the stored program pulse application number.
