ABSTRACT:
A data I/O circuit of a flash memory device includes a page buffer connected to at least one pair of bit lines, a page buffer select circuit arranged to output complementary input data, which is received through a pair of I/O lines, to the page buffer, or outputs complementary sensing data stored in the page buffer to the pair of I/O lines, in response to a buffer select signal, and a column select circuit arranged to output the complementary sensing data, which is received through the pair of I/O lines, to a pair of data I/O nodes, respectively, or to output the complementary input data, which is received through the pair of data I/O nodes, to the pair of I/O lines, in response to a column select signal and a gate control signal.
