Both L1 data cache and L2 memory can be configured either as random-access memory (RAM), cache, or part RAM/part cache.
The use of compression mechanisms to extend physical memory was first implemented in [11]; his proposal consisted in compressing LRU pages, keeping them in a RAM cache, and sending them to disk whenever needed.
When potentially modifiable data is requested, the RAM cache is inspected to see if there already exists any entry for the requested EHR ID, and if not, the latest EHR modification time and the ID of its associated CONTRIBUTION is fetched from the database and stored in the RAM cache.

Other system components, including the memory subsystem (RAM and cache), the graphics card and the hard disk, also affect the overall speed.
If you're counting, that's 1.5 GB of total RAM and RAM-like caches.
During the code review process, a close watch is also kept on memory consumption, since for large image sizes, transfers between computer memory (RAM) and CPU cache are often a serious performance bottleneck.
As well, look for a cache (RAM on a hard drive that stores frequently accessed information) of at least 8MB (16MB is better).
Also when comparing to the STT-RAM only L1 cache configuration, we reduce memory access latency nearly to 20% with close or even better energy consumption.
Eight PowerPC 604 processors, 112 Mhz, 1MB L2 cache each; 1 GB RAM; Ten GB internal disk space on five drives.
In May, after months of struggling to identify the cause, Sun found it had been shipping servers whose cache modules contained faulty S-RAM (static random access memory) chips from a supplierit won't name.
