ÐCache coherent nonuniform memory access (CC-NUMA) multiprocessors provide a scalable design for shared memory. But, they continue to suffer from large remote memory access latencies due to comparatively slow memory technology and large data transfer latencies in the interconnection network. In this paper, we propose a novel hardware caching technique, called switch cache, to improve the remote...

Cache coherent non-uniform memory access (CC-NUMA) multiprocessors provide a scal-able design for shared memory but they continue to suuer from large remote memory access latencies due to comparatively slow memory technology and data transfer latencies in the in-terconnection network. In this paper, we propose a novel hardware caching technique, called switch cache, to improve the remote memory...

Symptom Validity Testing (SVT) has been used effectively with sensory perception and short-term memory. The procedure was recently adapted to assess remote memory for specific events. Memory for remote events is particularly important to the criminal justice system, and courts are beginning to draw on neuropsychology to assist in the assessment of claimed remote memory loss. This report discuss...

Patients with Korsakoff's syndrome were evaluated with nine tests of new learning ability and three tests of remote memory to determine the correlation between anterograde amnesia and remote memory impairment. There was no correlation between the severity of anterograde amnesia and either the overall severity of remote memory impairment (1940s-1970s) or the impairment observed for more remote t...

In a cluster with a very low-latency interconnect, the remote memory of nodes can serve as a storage that is faster than local disk but slower than local memory. In this paper, we address the problem of transparently utilizing this cluster-wide pool of unused memory as a low-latency paging device. Such a transparent remote memory paging system can enable large-memory applications to benefit fro...

Some forms of memory have been shown to depend on a system of medial temporal lobe structures that includes the hippocampus and the adjacent cortical areas (entorhinal, perirhinal, and parahippocampal cortex). The role of this system is only temporary, however, as indicated by the fact that, after damage to the medial temporal lobe, recent memories are impaired but very remote memories are inta...

The hippocampus and surrounding regions of the medial temporal lobe play a central role in all neuropsychological theories of memory. It is still a matter of debate, however, how best to characterise the functions of these regions, the hippocampus in particular. In this article, I examine the proposal that the hippocampus is a "stupid" module whose specific domain is consciously apprehended inf...

In recent years, two separate research streams have focused on information sharing between the medial prefrontal cortex (mPFC) and hippocampus (HC). Research into spatial working memory has shown that successful execution of many types of behaviors requires synchronous activity in the theta range between the mPFC and HC, whereas studies of memory consolidation have shown that shifts in area dep...

Several studies have investigated the transition of consolidation of recent memory to remote memory in aversively motivated tasks, such as contextual fear conditioning (CFC) and inhibitory avoidance (IA). However, the mechanisms that serve the retrieval of remote memories, has not yet been fully understood. Some evidences suggest that the central cholinergic system appears be involved in the mo...

Long-lasting memories form the basis of our identity as individuals and lie central in shaping future behaviours that guide survival. Surprisingly, however, our current knowledge of how such memories are stored in the brain and retrieved, as well as the dynamics of the circuits involved, remains scarce despite seminal technical and experimental breakthroughs in recent years. Traditionally, it h...
