ABSTRACT:
A semiconductor memory device having an internal copy function. The memory device includes a memory cell array composed of a plurality of memory cells coupled to a plurality of bit lines, a plurality of column selectors coupled between the bit lines and an input/output data line for being turned on in response to a column select signal, a data amplifying circuit coupled to the input/output data line for amplifying the readout data, a data storage for receiving and latching the amplified data, and a write driver for outputting the latched data to the input/output data line.
