    摘要: Examples are disclosed for probabilistic dynamic random access memory (DRAM) row repair. In some examples, using a row hammer limit for DRAM and a maximum activation rate for the DRAM a probabilistic row hammer detection value may be determined. The probabilistic row hammer detection value may then be used such that a probability is acceptably low that a given activation to an aggressor row of the DRAM causes the row hammer limit to be exceeded before a scheduled row refresh is performed on one or more victim rows associated with the aggressor row. Other examples are described and claimed.

    摘要: A memory subsystem includes a group of memory devices connected to an address bus. The memory subsystem includes logic to uniquely map a physical address of a memory access command to each memory device of the group. Thus, each physical address sent by an associated memory controller uniquely accesses a different row of each memory device, instead of being mapped to the same or corresponding row of each memory device.

    摘要: In one embodiment, the present invention includes a method of assigning a location within a shared variable for each of multiple threads and writing a value to a corresponding location to indicate that the corresponding thread has reached a barrier. In such manner, when all the threads have reached the barrier, synchronization is established. In some embodiments, the shared variable may be stored in a cache accessible by the multiple threads. Other embodiments are described and claimed.

    摘要: Methods and apparatus to track the health of integrated circuit structures are described. In an embodiment, a counter may be updated when the status of a portion of a storage unit (e.g., a cache) transitions to a defective status (e.g., as determined by reference to one or more corresponding status bits). The value stored in the counter may be compared with a threshold value, e.g., to generate a signal that is indicative of whether the threshold value has been exceeded. Other embodiments are also described.

    摘要: An improved method of transferring burst data in a microprocessor is described. The improvement lies in the burst ordering of the data items to be referenced. The original address is selected as the data item that the user initially wants to access. Subsequent addresses in the burst are generated according to a mathematical algorithm. The algorithm generates the remaining addresses as a function of the internal bus width, the external memory/bus line size and the original address. Using the burst sequence of the present invention, memories/buses of different widths can be smoothly coupled to a microprocessor having a fixed CPU bus size (e.g., 32 bits).

    摘要: Apparatus for burning combustible particles to heat circulated air. The apparatus includes an upright housing containing a removable liner which forms the combustion chamber of the burner, and a perforated, intermediate wall member which forms, with the walls of the housing and the liner, outer and inner gas-receiving spaces, respectively. Air injected into the housing passes from the outer, into the inner gas-receiving space, where the gas is directed, through tuyeres in the liner, into the chamber, substantially tangentially to the wall thereof, producing a gas vortex therein. Particles introduced into the chamber through an upper opening are combusted primarily in the chamber's upper core region with such combustion being supported by, and acting to heat, vortexing gas within the chamber prior to its discharge through a lower chamber opening.
