2. Virtual memory compression - Wikipedia

   en.wikipedia.org/wiki/Virtual_memory_compression

   By reducing the I/O activity caused by paging requests, virtual memory compression can produce overall performance improvements. The degree of performance improvement depends on a variety of factors, including the availability of any compression co-processors, spare bandwidth on the CPU, speed of the I/O channel, speed of the physical memory, and the compressibility of the physical memory ...

3. HP-15C - Wikipedia

   en.wikipedia.org/wiki/HP-15C

   The calculator is also powered by two CR2032 batteries. The test menu (Off, g+↵ Enter+ON) officially offers three choices. A fourth choice (4) is undocumented and permits to enter two hidden modes: "15.2" (more memory, but with some limitations like 8×8 inversion matrices and three-digit step number display) and "16" (emulating a HP-16C).

4. Virtual memory - Wikipedia

   en.wikipedia.org/wiki/Virtual_memory

   Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".

5. HP-16C - Wikipedia

   en.wikipedia.org/wiki/HP-16C

   The calculator uses the proprietary HP Nut processor produced in a bulk CMOS process and featured continuous memory, whereby the contents of memory are preserved while the calculator is turned off. [13] Though commonplace now, this was still notable in the early 1980s, and is the origin of the "C" in the model name.

6. HP-19C/-29C - Wikipedia

   en.wikipedia.org/wiki/HP-19C/-29C

   HP-19C calculator HP-29C with AC-powered battery charger. The HP-19C and HP-29C were scientific/engineering pocket calculators made by Hewlett-Packard between 1977 and 1979. They were the most advanced and last models of the "20" family (compare HP-25) and included Continuous Memory (battery-backed CMOS memory) as a standard feature.

7. Memory virtualization - Wikipedia

   en.wikipedia.org/wiki/Memory_virtualization

   Virtual memory systems abstract between physical RAM and virtual addresses, assigning virtual memory addresses both to physical RAM and to disk-based storage, expanding addressable memory, but at the cost of speed. NUMA and SMP architectures optimize memory allocation within multi-processor systems. While these technologies dynamically manage ...
