Bitline precharge circuit of multi-sectional memory array

摘要

The invention relates to a bit line precharge circuit of a multi-sectional memory array in which a first set of circuits gate a section decoding signal and a main bit line precharge pulse and a second set of circuits gate the section decoding signal and a main data line precharge pulse. The resultant signals from the first and second sets of circuits are fed into respective inverter circuits and then respectively into a bit line precharge circuit and a data line precharge circuit so that the operation margin of the section decoding signal increases by as much as the width of the main bit line precharge pulse.
