    Abstract: An apparatus is disclosed that includes a memory controller chip and memory chips packaged with the memory controller chip. Each memory chip includes normal-retention storage rows that exhibit retention times greater or equal to a first time interval, and having been tested to generate information identifying low-retention storage rows that exhibit retention times less than the first time interval. Refresh logic refreshes the normal-retention storage rows at a first refresh rate corresponding to the first time interval, and refreshes each low-retention storage row at a second refresh rate that is greater than the first refresh rate.

    Abstract: A memory module is disclosed that includes a substrate, a memory device that outputs read data, and a buffer. The buffer has a primary interface for transferring the read data to a memory controller and a secondary interface coupled to the memory device to receive the read data. The buffer includes error logic to identify an error in the received read data and to identify a storage cell location in the memory device associated with the error. Repair logic maps a replacement storage element as a substitute storage element for the storage cell location associated with the error.

    Abstract: Systems, among other embodiments, include topologies (data and/or control/address information) between an integrated circuit buffer device (that may be coupled to a master, such as a memory controller) and a plurality of integrated circuit memory devices. For example, data may be provided between the plurality of integrated circuit memory devices and the integrated circuit buffer device using separate segmented (or point-to-point link) signal paths in response to control/address information provided from the integrated circuit buffer device to the plurality of integrated circuit buffer devices using a single fly-by (or bus) signal path. An integrated circuit buffer device enables configurable effective memory organization of the plurality of integrated circuit memory devices. The memory organization represented by the integrated circuit buffer device to a memory controller may be different than the actual memory organization behind or coupled to the integrated circuit buffer device. The buffer device segments and merges the data transferred between the memory controller that expects a particular memory organization and actual memory organization.
