    摘要: A high speed DRAM cache architecture. One disclosed embodiment includes a multiplexed bus interface to interface with a multiplexed bus. A cache control circuit drives a row address portion of an address on the multiplexed bus interface and a command to open a memory page containing data for a plurality of ways. The cache control circuit subsequently drives a column address including at least a way indicator to the multiplexed bus interface.

    摘要: Methods and apparatuses for mapping cache contents to memory arrays. In one embodiment, an apparatus includes a processor portion and a cache controller that maps the cache ways to memory banks. In one embodiment, each bank includes data from one cache way. In another embodiment, each bank includes data from each way. In another embodiment, memory array banks contain data corresponding to sequential cache lines.

    摘要: Embodiments of the invention are generally directed to systems, methods, and apparatuses for a common memory device for variable device width and scalable pre-fetch and page size. In some embodiments, a common memory device (such as a DRAM) can operate in any of a number of modes including, for example, a x4 mode, a x8 mode, and a x16 mode. The page size provided by the DRAM may vary depending on the mode of the DRAM. In some embodiments, the amount of data pre-fetched by the DRAM also varies depending on the mode of the DRAM.
