    摘要: The present disclosure provides a method for processing memory access operations. The method includes determining a fixed response time based at least in part, on a total memory latency of a memory module. The method also includes identifying an available time slot for receiving return data from the memory module over a data bus, wherein the time difference between a current clock cycle and the available time slot is greater than or equal to the fixed response time. The method also includes creating a first slot reservation by reserving the available time slot. The method also includes issuing as read request to the memory module over the data bus, wherein the read request is issued at a clock cycle determined by subtracting the fixed response time from a time of the first slot reservation.

    摘要: A shiftable memory employs row shifting to shift data along a row. The shiftable memory includes memory cells arranged as a plurality of rows and a plurality of columns. The shiftable memory further includes shift logic to shift data from an output of a first column to an input of a second column. The shifted data is provided by a memory cell of the first column in a selected row. The shifted data is received and stored by a memory cell in the selected row of the second column. The shift logic facilitates shifting data along the selected row.

    摘要: Example methods, apparatus, and articles of manufacture to perform error detection and correction are disclosed. A disclosed example method involves enabling a memory controller to operate in one of a tagged memory mode or a non-tagged memory mode. In addition, when the tagged memory mode is enabled in the memory controller, a five-error-correction-six-error-detection per-burst mode is selected to perform error correction on data. When the non-tagged memory mode is enabled in the memory controller, one of a six-error-correction-seven-error-detection per-burst mode or a single-error-correction-dual-error-detection per-transfer mode is selected based on a pattern of error types in the data.

    摘要: Embodiments herein relate to a method for remapping data. In an embodiment, it is determined if a first memory block is faulty. A pointer is stored to the first memory block and a pointer flag of the first memory block is set when the first memory block is faulty. Data previously stored at the first memory block is written to a second memory block, where the pointer points to a location of the second memory block.
