20130329480 | SRAM - The SRAM memory cell includes a metal wiring line having a titanium or tantalum film in a bottom layer, and a via having a tungsten plug. The via is arranged on the metal line following a layout rule which permits the misalignment. In arranging the upper-layer via with a tungsten plug on the metal line, one side of the via is disposed to be adjacent to one end of the metal line with a margin smaller than an alignment accuracy, and the lower-layer via is laid out far away from the end of the metal line as possible. The reduction in the yield, caused by the problem of the contact with the lower-layer via being broken or increased in resistance at occurrence of misalignment, can be suppressed. | 2013-12-12 |

The first semiconductor chip includes a first terminal, a second terminal, a first circuit electrically coupled to the second terminal, a second circuit electrically coupled to the first terminal and the first circuit, and a third circuit electrically coupled to the second circuit. The second semiconductor chip includes a third terminal, a fourth terminal, a fourth circuit electrically coupled to the fourth terminal, a fifth circuit electrically coupled to the third terminal and the fourth circuit, and a sixth circuit electrically coupled to the fifth circuit. | 2013-12-12 |
20130329482 | HIGH BANDWIDTH MEMORY INTERFACE - A memory module that includes a buffer and a plurality of synchronous memory devices. The memory module also includes bidirectional bus lines, and each of the synchronous memory devices has bidirectional data terminals. The buffer is configured to regenerate signals received on the bus lines for receipt by the synchronous memory devices, and to regenerate signals received from any one of the synchronous memory devices for receipt by the bus lines. The memory module may further include command lines and a clock line for providing commands and a clock signal to the synchronous memory devices via a command buffer. The combined data bus width of the memory module may be greater than the data bus width of any single one of synchronous memory device, and the total address space provided by the memory module may be larger than the data space for any single synchronous memory device. | 2013-12-12 |
