Abstract
A semiconductor device includes a memory array including memory cells, page buffers suitable for reading data from the memory cells, cache latch circuits suitable for latching read data from the page buffers, and transmitting latched data to data lines in response to a column selection signal, a column selector suitable for outputting the column selection signal to the cache latch circuits through column selection lines in response to a column address, and sense amplifiers suitable for outputting transmitted data of the data lines by sensing voltages of the data lines, in which the cache latch circuits are connected to the column selector and the sense amplifiers through the column selection lines and the data lines, respectively, and have inverse relationship between the column selection lines and the data lines in length.
