    摘要: A design structure is provided for a memory module containing an interface for receiving memory access commands from an external source, in which a first portion of the interface receives memory access data at a first bus frequency and a second portion of the interface receives memory access data at a second different bus frequency. Preferably, the memory module contains a second interface for re-transmitting memory access data, also operating at dual frequency. The memory module is preferably used in a high-capacity memory subsystem organized in a tree configuration in which data accesses are interleaved. Preferably, the memory module has multiple-mode operation, one of which supports dual-speed buses for receiving and re-transmitting different parts of data access commands, and another of which supports conventional daisy-chaining.

    摘要: A method, apparatus and program product enable memory compression for a system including processor with directly attached memory. A memory expander microchip facilitates memory compression while attached to a processor. The memory expander microchip may provide additional bandwidth and memory capacity for the system to enable memory compression in a manner that does not burden the attached processor or associated operating system. The processor may store uncompressed data in its lower latency, directly attached memory, while the memory attached to the memory expander may store either or both compressed and uncompressed data.

    摘要: A random access memory device includes an array of individual memory cells arranged into rows and columns, each memory cell having an access device associated therewith. Each row of the array further includes a plurality of N word lines associated therewith, with a wherein N corresponds to a number of independently accessible partitions of the array, wherein each access device in a given row is coupled to only one of the N word lines of the row. Address decoder logic in signal communication with the array is configured to receive a plurality of row address bits and determine, for a requested row identified by the row address bits, which of the N partitions within the requested row are to be accessed, such that access devices within a selected row, but not within a partition to be accessed, are not activated.

    摘要: Systems and methods to manage memory are provided. A particular method may include initiating a memory compression operation. The method may further include initiating a first interrupt configured to affect a first process executing on a processor in response to a first detected memory level. A second initiated interrupt may be configured to affect the first process executing on the processor in response to a second detected memory level, and a third interrupt may be initiated to affect the first process executing on the processor in response to a third detected memory level. At least of the first, the second, and the third detected memory levels are affected by the memory compression operation.
