  3. Moore's law - Wikipedia

    en.wikipedia.org/wiki/Moore's_law

    Eroom's law – is a pharmaceutical drug development observation that was deliberately written as Moore's Law spelled backwards in order to contrast it with the exponential advancements of other forms of technology (such as transistors) over time. It states that the cost of developing a new drug roughly doubles every nine years.

  4. Conventional memory - Wikipedia

    en.wikipedia.org/wiki/Conventional_memory

    It is the read-write memory directly addressable by the processor for use by the operating system and application programs. As memory prices rapidly declined, this design decision became a limitation in the use of large memory capacities until the introduction of operating systems and processors that made it irrelevant.

  7. DRAM price fixing scandal - Wikipedia

    en.wikipedia.org/wiki/DRAM_price_fixing_scandal

    DRAM SO-DIMM. In 2002, the United States Department of Justice, under the Sherman Antitrust Act, began a probe into the activities of dynamic random-access memory (DRAM) manufacturers in response to claims by US computer makers, including Dell and Gateway, that inflated DRAM pricing was causing lost profits and hindering their effectiveness in the marketplace.

  8. Average memory access time - Wikipedia

    en.wikipedia.org/wiki/Average_memory_access_time

    AMAT's three parameters hit time (or hit latency), miss rate, and miss penalty provide a quick analysis of memory systems. Hit latency (H) is the time to hit in the cache. Miss rate (MR) is the frequency of cache misses, while average miss penalty (AMP) is the cost of a cache miss in terms of time. Concretely it can be defined as follows.

  9. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    (For example, if a computer has 2 GB (1024 3 B) of RAM and a 1 GB page file, the operating system has 3 GB total memory available to it.) When the system runs low on physical memory, it can " swap " portions of RAM to the paging file to make room for new data, as well as to read previously swapped information back into RAM.
