SERIAL FLASH MEMORY DEVICE AND PRECHARGING METHOD THEREOF
摘要
<p>Provided herein is a serial flash memory device and precharging method thereof in which a single local bit-line data is sensed in synchronization with a clock. The method includes precharging two or more local bit-lines in synchronization with a first clock; and disprecharging one of the two local bit-lines in synchronization with a second clock and sensing and amplifying data of the other local bit-line. Accordingly, two precharged local bit-lines are not adjacent to each other, thereby eliminating a coupling noise effect. In addition, the time for performing the precharging operation and the sensing operation is easily secured, compared to the prior precharging method in which corresponding local bit-lines are precharged at every clock.</p>
