Patent ID: 7512011

Claim:
A method of reading data in a non-volatile memory device, the method comprising: providing a plurality of blocks and a plurality of bit lines, each block having a plurality of memory cells, each block coupled to at least one bit line; discharging first and second bit lines to be at a low level, the first bit line coupled to a first block, the second bit line coupled to a second block; applying a read voltage to a first word line coupled to a memory cell to be read in the first block; applying a pass voltage to a second word line coupled to a memory cell not to be read in the first block; precharging the first bit line coupled to the memory cell to be read to a high level after applying the read voltage to the first word line and the pass voltage to the second word line; evaluating a voltage level of the first bit line; and sensing data stored in the memory cell to be read in accordance with the evaluated voltage level of the first bit line.
