Burst read mode word line boosting

摘要

A burst read mode operation is provided that boosts the voltage of a word line while the bit lines of the row are selected for reading. When the column group address bits read the last column group of cells in the row, a pulse signal is generated which temporarily reduces the boosted voltage to allow the X-decoder to select the next word line. An alternative delay element is also provided which generates an ATD pulse with a longer duration when the column group address bits are at the end of a row and a shorter duration pulse at other times.
