Abstract
A flash memory device implements a sequential read method using overlapping read cycles to initiate the bit-line precharge and equalization operation for a next memory cell address prior to the completion of the read cycle of the current memory cell address. More specifically, the sequential read method implements overlapping read cycle where the bit-line precharge and equalization operation is started for a memory cell of the next address while the memory cell of the current address is being read out. In this manner, the read speed for the sequential read operation of the flash memory device is improved. In some embodiments, the memory cell array for each input-output (I/O) of the flash memory device is partitioned into two sub-banks to further reduce the read cycle time by enabling early activation of the word-line for the next sub-bank.
