Abstract
A semiconductor memory that reduces the amount of power consumed by an entire unit by decreasing a charging/discharging current. A row direction selection circuit selects predetermined memory cell groups in a row direction in response to a row input address signal. A column direction selection circuit selects predetermined memory cell groups in a column direction in response to a column input address signal. Connection-disconnection circuits connect a divided bit line corresponding to a column selected by the column direction selection circuit of divided bit lines connected to memory cell groups, respectively, selected by the row direction selection circuit to the corresponding common bit line and do not connect divided bit lines corresponding to the other columns.
