  2. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    The memory cell is the fundamental building block of computer memory. The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level). Its value is maintained/stored until it is changed by the set/reset process.

  3. Retrograde signaling - Wikipedia

    en.wikipedia.org/wiki/Retrograde_signaling

    For example, the nucleus of a cell is the original source for creating signaling proteins. During retrograde signaling, instead of signals leaving the nucleus, they are sent to the nucleus. [ 1 ] In cell biology , this type of signaling typically occurs between the mitochondria or chloroplast and the nucleus.

    For example a stick of RAM that has only 512 megabytes of transfer speed is too slow compared to a stick of RAM that has 16 gigabytes of transfer speeds. [5] Not only does the transfer speeds depend of how fast a RAM can process information, the type of stick of RAM depends as well. For example, there are sticks that can be used DDR3, DDR4 and ...

  5. Magnetoresistive RAM - Wikipedia

    en.wikipedia.org/wiki/Magnetoresistive_RAM

    One of the two plates is a permanent magnet set to a particular polarity; the other plate's magnetization can be changed to match that of an external field to store memory. This configuration is known as a magnetic tunnel junction (MTJ) and is the simplest structure for an MRAM bit. A memory device is built from a grid of such "cells".

  6. Resistive random-access memory - Wikipedia

    en.wikipedia.org/wiki/Resistive_random-access_memory

    Resistive random-access memory (ReRAM or RRAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance across a dielectric solid-state material, often referred to as a memristor. One major advantage of ReRAM over other NVRAM technologies is the ability to scale below 10 nm.

  7. Phase-change memory - Wikipedia

    en.wikipedia.org/wiki/Phase-change_memory

    Phase-change memory (also known as PCM, PCME, PRAM, PCRAM, OUM (ovonic unified memory) and C-RAM or CRAM (chalcogenide RAM)) is a type of non-volatile random-access memory. PRAMs exploit the unique behaviour of chalcogenide glass .

    A memory controller, also known as memory chip controller (MCC) or a memory controller unit (MCU), is a digital circuit that manages the flow of data going to and from a computer's main memory. [ 1 ] [ 2 ] When a memory controller is integrated into another chip, such as an integral part of a microprocessor , it is usually called an integrated ...
