  2. Memory architecture - Wikipedia

    en.wikipedia.org/wiki/Memory_architecture

    Memory architecture describes the methods used to implement electronic computer data storage in a manner that is a combination of the fastest, most reliable, most durable, and least expensive way to store and retrieve information. Depending on the specific application, a compromise of one of these requirements may be necessary in order to ...

    Historical lowest retail price of computer memory and storage Electromechanical memory used in the IBM 602, an early punch multiplying calculator Detail of the back of a section of ENIAC, showing vacuum tubes Williams tube used as memory in the IAS computer c. 1951 8 GB microSDHC card on top of 8 bytes of magnetic-core memory (1 core is 1 bit.)

  4. x86 memory models - Wikipedia

    en.wikipedia.org/wiki/X86_memory_models

    Four registers are used to refer to four segments on the 16-bit x86 segmented memory architecture. DS (data segment), CS (code segment), SS (stack segment), and ES (extra segment). Another 16-bit register can act as an offset into a given segment, and so a logical address on this platform is written segment:offset, typically in hexadecimal ...

  5. Memory hierarchy - Wikipedia

    en.wikipedia.org/wiki/Memory_hierarchy

    In computer architecture, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity , and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [ 1 ]

  6. Memory cell (computing) - Wikipedia

    en.wikipedia.org/wiki/Memory_cell_(computing)

    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).

  7. Computer architecture - Wikipedia

    en.wikipedia.org/wiki/Computer_architecture

    The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.

  8. 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.

  9. Modified Harvard architecture - Wikipedia

    en.wikipedia.org/wiki/Modified_Harvard_architecture

    A modified Harvard architecture is a variation of the Harvard computer architecture that, unlike the pure Harvard architecture, allows memory that contains instructions to be accessed as data. Most modern computers that are documented as Harvard architecture are, in fact, modified Harvard architecture.
