Abstract
A semiconductor memory device for storing data defining a multidimensional space based on coordinate information of the data, includes: a cell array having memory cells arranged in a lattice pattern, for storing the data; a word line selector selecting and driving any one of a plurality of word lines which activate memory cells arranged in a row direction; write amplifiers/sense amplifiers writing/reading data to/from the memory cells arranged in a column direction; an amplifier selector inputting/outputting the data to/from the selected one of the write amplifiers/sense amplifiers; and an address conversion circuit generating a row address to be supplied to the word line selector based on the coordinate information of the data, and to generate a column address to be supplied to the amplifier selector by converting the coordinate information of the data into one-dimensional information.
