Abstract
A semiconductor device and a data storage apparatus are provided. A semiconductor device includes: a cell array configured to have cells for data storage arranged in an array; at least one buffer configured to latch read data of the cell array in units of pages; an output circuit configured to output read data; and a data transfer circuit configured to sequentially transfer read data in units of pages latched in the buffer to the output circuit, wherein the data transfer circuit includes: at least one layer of a scan register train including a plurality of serially connected scan registers having a register and a multiplexer connected to each other to operate for each of clocks, wherein an output of the multiplexer is connected to an input of a register, and an input of a multiplexer is connected to an output of a register in a next previous stage.
