The controller is configured to execute a transcribe operation in which the storage data temporarily stored in the buffer memory is selectively stored in the storage medium. Further, the controller is responsive to receipt of the invalidation command to execute a logging process when a memory capacity of the invalid data indicated by the invalidation command is equal to or greater than a reference capacity, and to execute an invalidation process when the memory capacity of the invalid data is less than the reference capacity. The logging process includes logging a location of the invalid data, and the invalidation process includes invalidating the invalid data. | 2010-08-26 |
| 20100217928 | Semiconductor Memory Asynchronous Pipeline - An asynchronously pipelined SDRAM has separate pipeline stages that are controlled by asynchronous signals. Rather than using a clock signal to synchronize data at each stage, an asynchronous signal is used to latch data at every stage. The asynchronous control signals are generated within the chip and are optimized to the different latency stages. Longer latency stages require larger delays elements, while shorter latency states require shorter delay elements. The data is synchronized to the clock at the end of the read data path before being read out of the chip. Because the data has been latched at each pipeline stage, it suffers from less skew than would be seen in a conventional wave pipeline architecture. Furthermore, since the stages are independent of the system clock, the read data path can be run at any CAS latency as long as the re-synchronizing output is built to support it. | 2010-08-26 |
| 20100217929 | Using External Memory Devices to Improve System Performance - The invention is directed towards a system and method that utilizes external memory devices to cache sectors from a rotating storage device (e.g., a hard drive) to improve system performance. When an external memory device (EMD) is plugged into the computing device or onto a network in which the computing device is connected, the system recognizes the EMD and populates the EMD with disk sectors. The system routes I/O read requests directed to the disk sector to the EMD cache instead of the actual disk sector. The use of EMDs increases performance and productivity on the computing device systems for a fraction of the cost of adding memory to the computing device. | 2010-08-26 |
