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, ...

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 ...

To prevent CPUs from using outdated data in their caches instead of using the updated data in RAM or a neighboring cache, a feature called bus snooping was introduced.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

Clearly, when government IT departments incorporate in-memory computing with a fast restartability store, they can store environment-specific data in the cache, using a simple put/get API and ...

Cache data needs all this housekeeping data — the tag, the valid bit, the dirty bit — stored in high-speed cache memory, which increases the overall cost of the cache system.

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 ...

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 ...

NoSQL data stores offer alternative data storage options for non-relational data types like document based, object graphs, and key-value pairs. Can a distributed cache be used as a NoSQL store ...
