  • Patent number: 9349652
    Abstract: A method for fabricating a semiconductor device includes forming a first gate stack over a first fin feature and second gate stack over a second fin feature, removing the first gate stack to form a first gate trench that exposes the first fin structure, removing the second gate stack to form a second gate trench that exposes the second fin feature, performing an annealing process to change a composition of a portion of the first fin feature and forming a first high-k/metal gate (HK/MG) within the first gate trench over the portion of the first fin feature and a second HK/MG within the second gate trench over the second fin feature. Therefore the first HK/MG is formed with a first threshold voltage and the second HK/MG is formed with a second threshold voltage, which is different than the first threshold voltage.

  • Publication number: 20150381769
    Abstract: A server, a server management system and a server management method are disclosed. The server comprises a field replaceable unit (FRU) memory and a baseboard management controller (BMC). The FRU memory stores an FRU data. The BMC receives an FRU access command from a remote management computer via an intelligent platform management interface (IPMI). The FRU access command comprises an FRU identification (ID). The BMC determines whether the FRU ID belongs to the FRU memory. If the FRU ID does not belong to the FRU memory, the BMC accesses a custom file according to the FRU ID. The custom file is different from the FRU data.

    Abstract: Examples are disclosed for accessing a dynamic random access memory (DRAM) array. In some examples, sub-arrays of a DRAM bank may be capable of opening multiple pages responsive to a same column address strobe. In other examples, sub-arrays of a DRAM bank may be arranged such that input/output (IO) bits may be routed in a serialized manner over an IO wire. For these other examples, the IO wire may pass through a DRAM die including the DRAM bank and/or may couple to a memory channel or bus outside of the DRAM die. Other examples are described and claimed.
