Patent ID: 7907473

Claim:
A semiconductor memory device to store data defining a multidimensional space, based on coordinate information of the data, the semiconductor device comprising: a cell array including memory cells arranged in a lattice pattern to store the data; a word line selector selecting and driving any one of a plurality of word lines to activate the memory cells arranged in a row direction; a plurality of write amplifiers and a plurality of sense amplifiers writing and reading the data to and from the memory cells, respectively, arranged in a column direction; an amplifier selector selecting any one of a plurality of pairs of the write amplifiers and the sense amplifiers to input and output the data to and from the selected one of the plurality of pairs of the write amplifiers and the sense amplifiers, respectively; 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.
