FLASH MEMORY DEVICE SHARING A HIGH VOLTAGE GENERATOR

摘要

A flash memory device sharing a high voltage generator is provided to reduce chip area by reducing the number of high voltage pump circuits. A cell array(140) includes memory cells connected to a plurality of word lines. A voltage generator generates a first voltage provided to unselected word lines among the plurality of word lines during program operation, and a second voltage provided to the unselected word lines during program verification operation. The second voltage is lower than the first voltage. The voltage generator generates the first voltage and the second voltage through an equal charge pump circuit.
