  2. Memory controller - Wikipedia

    en.wikipedia.org/wiki/Memory_controller

    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 ...

    The DMA controller then provides addresses and read/write control lines to the system memory. Each time a byte of data is ready to be transferred between the peripheral device and memory, the DMA controller increments its internal address register until the full block of data is transferred.

  4. Von Neumann architecture - Wikipedia

    en.wikipedia.org/wiki/Von_Neumann_architecture

    A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.

    Block diagram of the Platform Controller Hub–based chipset architecture, including an Integrated Memory Controller (IMC) in the CPU An Intel DH82H81 PCH with its die exposed. The Platform Controller Hub (PCH) is a family of Intel's single-chip chipsets, first introduced in 2009.

  6. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    If the address field is non-zero, it is a disk address of the block, which has previously been rolled out — the block is fetched from disk, the pbit is set to one and the physical memory address updated to point to the block in memory. This makes descriptors equivalent to a page-table entry in an MMU system, but descriptors are free of a table.

  7. 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). Its value is maintained/stored until it is changed by the set/reset process.

  8. Intel 8237 - Wikipedia

    en.wikipedia.org/wiki/Intel_8237

    Intel 8237A-5, used on the original IBM PC motherboard Pinout. Intel 8237 is a direct memory access (DMA) controller, a part of the MCS 85 microprocessor family. It enables data transfer between memory and the I/O with reduced load on the system's main processor by providing the memory with control signals and memory address information during the DMA transfer.

  9. Flash memory controller - Wikipedia

    en.wikipedia.org/wiki/Flash_memory_controller

    Usually, flash memory controllers also include the "flash translation layer" (FTL), a layer below the file system that maps host side or file system logical block addresses (LBAs) to the physical address of the flash memory (logical-to-physical mapping). The LBAs refer to sector numbers and to a mapping unit of 512 bytes.
