  • Publication number: 20160077974
    Abstract: Technologies are described herein for adaptively controlling the size of a write cache in a storage device based on the time required to flush the cache. Upon receiving a write command at a controller for the storage device, an estimated cache flush time for the write cache is calculated based on the write commands contained therein. If the estimated cache flush time is greater than a maximum threshold time, the size of the write cache is decreased to control the cache flush time. If the estimated cache flush time is less than a minimum threshold time, the size of the write cache is increased to enhance random write performance.

  • Publication number: 20150364574
    Abstract: In a method of manufacturing a semiconductor device, a dummy gate structure including a dummy gate insulation layer pattern, a dummy gate electrode and a gate mask sequentially stacked are formed on a substrate. An interlayer insulating layer including tonen silazane (TOSZ) is formed on the substrate to cover the dummy gate structure. An upper portion of the interlayer insulating layer is planarized until a top surface of the gate mask is exposed to form an interlayer insulating layer pattern. The exposed gate mask, and the dummy gate electrode and the dummy gate insulation layer pattern under the gate mask are removed to form an opening exposing a top surface of the substrate. The dummy gate insulation layer pattern is removed using an etchant including hydrogen fluoride (HF), but the interlayer insulating layer pattern remains.
