SEMICONDUCTOR MEMORY DEVICE AND ADDRESS DETERMINATION METHOD THEREOF

摘要

A semiconductor memory device and an address determination method thereof are provided to reduce signal distortion and power consumption, by decreasing the length of a bit line. A plurality of sub arrays(100) include memory cells arranged in rows and columns. A pre-decoder circuit outputs a decoded row address by receiving a row address. A block selection circuit generates a selection signal to select each sub array by receiving 2 bits of most significant bits of the row address. A row decoder(110) corresponds to each sub array, and selects rows of a sub array corresponding to a corresponding selection signal outputted from the block selection circuit and the output of the pre-decoder circuit.
