Abstract
A NAND type flash memory device has a reference bit line and a reference page buffer to control sensing time during program and erase verification operations. Each reference memory cell in the reference bit line is pre-programmed with a reference bit. A set initiation signal triggers detection and latching of the reference bit by the reference page buffer. When the reference bit is latched, an output of the reference page buffer is used as a set signal to trigger the program and erase verification operations of corresponding memory cells.
