  2. Memory scrubbing - Wikipedia

    en.wikipedia.org/wiki/Memory_scrubbing

    Memory scrubbing consists of reading from each computer memory location, correcting bit errors (if any) with an error-correcting code , and writing the corrected data back to the same location. [ 1 ] Due to the high integration density of modern computer memory chips , the individual memory cell structures became small enough to be vulnerable ...

  3. Memory Reference Code - Wikipedia

    en.wikipedia.org/wiki/Memory_Reference_Code

    The MRC is part of reference BIOS code, which relates to memory initialization in the BIOS. It includes information about memory settings, frequency, timing, driving and detailed operations of the memory controller. The MRC is written in a C-language code, which can be edited and compiled by board makers. It provides a space to develop advanced ...

  4. 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.

  5. Memory timings - Wikipedia

    en.wikipedia.org/wiki/Memory_timings

    The time to read the first bit of memory from a DRAM without an active row is T RCD + CL. Row Precharge Time T RP: The minimum number of clock cycles required between issuing the precharge command and opening the next row. The time to read the first bit of memory from a DRAM with the wrong row open is T RP + T RCD + CL. Row Active Time T RAS

  7. Serial presence detect - Wikipedia

    en.wikipedia.org/wiki/Serial_presence_detect

    In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.

  8. Gaming computer - Wikipedia

    en.wikipedia.org/wiki/Gaming_computer

    A gaming computer, also known as a gaming PC, is a specialized personal computer designed for playing PC games at high standards. They typically differ from mainstream personal computers by using high-performance graphics cards , a high core-count CPU with higher raw performance and higher-performance RAM .

  9. Static random-access memory - Wikipedia

    en.wikipedia.org/wiki/Static_random-access_memory

    RAM with an access time of 70 ns will output valid data within 70 ns from the time that the address lines are valid. Some SRAM cells have a page mode, where words of a page (256, 512, or 1024 words) can be read sequentially with a significantly shorter access time (typically approximately 30 ns). The page is selected by setting the upper ...
