Abstract

Disclosed is a method and semiconductor circuit for providing a read operation in a NAND flash memory. The NAND flash memory includes an array of bit lines. The method includes selecting a first set of bit lines of the array of bit lines for performing the read operation. The first set of bit lines are pre-charged to a pre-defined voltage level. At the same time, a second set of bit line are also charged to the pre-defined voltage. The second set of bit lines are in anti-phase to the first set of bit lines. Further, reading of the first set of bit-lines is performed. The second set of bit lines is maintained at the pre-defined voltage level during the reading of the first set of bit lines.
