OVER DRIVING PULSE GENERATOR AND MEMORY DEVICE WHICH INCLUDE PULSE GENERATOR

摘要

An over driving pulse generator and a memory device including the same are provided to control the width of a pulse according to the variation of a power supply voltage. A bit line sense amplifier(310) amplifies a voltage difference between a pair of bit lines. A sense amplifier driving part(320) supplies a driving voltage to the bit line sense amplifier in order to enable the bit line sense amplifier. An over driving control part(330) adjusts the size of a high voltage supply period for over driving supplied by the sense amplifier part according to the variation of a power supply voltage. The over driving control part comprises an over driving pulse generation unit to generate a pulse signal with pulse width adjusted according to the level variation of the power supply voltage.
