摘要:
Examples are disclosed for determining a logical address of one or more victim rows of a volatile memory based on a logical address of an aggressor row and address translation schemes associated with the volatile memory. 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.

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.

Systems and techniques for virtual device sharing. A failure of one of a plurality of memory devices corresponding to a first rank in a memory system is detected. The memory system has a plurality of ranks, each rank having a plurality of memory devices used to store a cache line. A portion of the cache line corresponding to the failed memory device is stored in a memory device in a second rank in the memory system and the remaining portion of the cache line in the first rank of the memory system.
摘要:
A processor implementing techniques for supporting configurable security levels for memory address ranges is disclosed. In one embodiment, the processor includes a processing core a memory controller, operatively coupled to the processing core, to access data in an off-chip memory and a memory encryption engine (MEE) operatively coupled to the memory controller. The MEE is to responsive to detecting a memory access operation with respect to a memory location identified by a memory address within a memory address range associated with the off-chip memory, identify a security level indicator associated with the memory location based on a value stored on a security range register. The MEE is further to access at least a portion of a data item associated with the memory address range of the off-chip memory in view of the security level indicator.

摘要:
An electrical connector backshell assembly may include at least one cable containing at least one electrical wire that is protected by a shield, at least a portion of the shield being separable from the at least one electrical wire. The backshell assembly also may include a housing defining an opening configured to receive the at least one cable and a termination area electrically coupled to the housing. The separable portion of the shield may be urged into contact with the termination area.
