US Patent 7272042 Semiconductor integrated circuit device

A semiconductor integrated circuit device includes a global-bit line, first and second section bit lines, a first transistor which connects the global bit line with the first section bit line, a second transistor which connects the global bit line with the second section bit line, a section selection circuit which selects one of the first and the second transistors, and a data latch circuit. The data latch circuit includes a data amplifier circuit which amplifies readout data from the first and the second section bit lines, a first data holding circuit which holds readout data and programming data to the first section bit line, and a second data holding circuit which holds readout data and programming data to the second section bit line.
