Latest Patents
Obara's latest patents focus on enhancing the operation of DRAM while reducing power consumption. One of his key inventions involves a semiconductor integrated circuit device that includes a pair of precharge MOSFETs. These MOSFETs supply a precharge voltage to input/output nodes of a CMOS sense amplifier. The design connects these nodes to a complementary bit-line pair through a selection switch MOSFET. Additionally, a first equalize MOSFET is integrated to equalize the complementary bit-line pair. The memory cell is strategically placed between one of the complementary bit-line pairs and a word line that intersects with it. The gate insulators of the selection switch MOSFETs and the first equalize MOSFET are formed with a specific film thickness, while the precharge MOSFET features a thinner gate insulator. This innovative design allows for the efficient supply of precharge and equalize signals, significantly improving the performance of DRAM systems.
