A plurality of cells are connected to one bit line MBL_. Each cell includes a sub bit line SBL_n_m and 4 to 64 memory cells (a memory cell CL_n_m_1 or the like). Further, each cell includes selection transistors STr1_n_m and STr2_n_m and an amplifier circuit AMP_n_m that is a complementary inverter or the like is connected to the selection transistor STr2_n_m. Since parasitic capacitance of the sub bit line SBL_n_m is sufficiently small, potential change due to electric charge in a capacitor of each memory cell can be amplified by the amplifier circuit AMP_n_m without an error, and can be output to the bit line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device and method for driving the same","description":"In a conventional DRAM, when the capacitance of a capacitor is reduced, an error of reading data easily occurs.
