Abstract
A nonvolatile memory device includes a memory cell, a bit line, a page buffer, and a control logic. The page buffer is connected to the memory cell through the bit line and the page buffer is configured to precharge the bit line to perform a desired operation. The desired operation may be one of a read operation and a verify operation. The control logic is configured to control bit line development time differently according to a temperature after precharging the bit line during the desired operation. The control logic is configured to determine the bit line development time according to a period of a reference clock signal that includes a different frequency depending on the temperature and/or a temperature compensation pulse signal including a pulse width that varies based on the temperature.
