<p>Disclosed is a dual-substrate stack memory in which: memory cell arrays, sense amplifiers for recording data on the memory cell arrays or reading the data recorded on the memory cell array, and write driving units are implemented in one substrate; and a buffer for temporarily storing data read from the memory cell arrays or temporarily storing data to be recorded on the memory cell arrays is implemented in the other substrate, so as to use the substrates by electrically bonding the substrates. The dual-substrate stack memory, according to the present invention, has a first substrate and a second substrate of which upper surfaces are bonded with each other or an upper surface and a lower surface are bonded.</p> |
