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To prevent CPUs from using outdated data in their caches instead of using the updated data in RAM or a neighboring cache, a feature called bus snooping was introduced.

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.

Put simply, SSD caching uses flash storage as cache memory to store frequently accessed data. Whenever data from the primary storage (the drive being cached) is accessed, the data is also stored in ...

Most users will not notice a drop in performance with a DRAM-less SSD, but it still might be getting less and less worthwhile ...

However in recent years, the cost of memory has been falling, making it possible to put far larger datasets in memory for data processing tasks, rather than use it simply as a cache.

Currently, TMO enables transparent memory offloading across millions of servers in our datacenters, resulting in memory savings of 20%–32%. Of this, 7%–19% is from the application containers, while ...

However, this may cause significant overheads for metadata storage and traffic. While using a fixed-size, near-memory cache and compressing data in near memory can help, precious near-memory capacity ...

IBM Research has been working on new non-volatile magnetic memory for over two decades. Non-volatile memory is wonderful for retaining data without power, but it is extremely slow, and does not ...
