Cache, in its crude definition, is a faster memory which stores copies of data from frequently used main memory locations. Nowadays, multiprocessor systems are supporting shared memories in hardware, ...

To prevent CPUs from using outdated data in their caches instead of using the updated data in RAM or a neighboring cache, a feature called bus snooping was introduced.

Write-through: all cache memory writes are written to main memory, even if the data is retained in the cache, such as in the example in Figure 4.11. A cache line can be in two states – valid or ...

One of the key challenges in chip multi-processing is to provide a programming model that manages cache coherency in a transparent and efficient way. A large number of applications designed for ...

Cache and memory in the many-core era As CPUs gain more cores, resource management becomes a critical performance … ...

BANGALORE, INDIA: In-memory database systems (IMDSs) store records in main memory, they never go to disk. Through this elimination of disk access, IMDSs claim significant performance gains over ...

Optane Memory uses a "least recently used" (LRU) approach to determine what gets stored in the fast cache. All initial data reads come from the slower HDD storage, and the data gets copied over to ...

Instead of more memory or a better cache, a better data architecture is needed. To achieve instantaneous decision-making, digital enterprises require a new hybrid memory architecture that processes ...
