  2. C dynamic memory allocation - Wikipedia

    en.wikipedia.org/wiki/C_dynamic_memory_allocation

    The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.

  3. Dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Dynamic_random-access_memory

    Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...

  4. Free list - Wikipedia

    en.wikipedia.org/wiki/Free_list

    A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation. It operates by connecting unallocated regions of memory together in a linked list, using the first word of each unallocated region as a pointer to the next. It is most suitable for allocating from a memory pool, where all objects have the same size.

  5. Memory management - Wikipedia

    en.wikipedia.org/wiki/Memory_management

    Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.

  6. Memory architecture - Wikipedia

    en.wikipedia.org/wiki/Memory_architecture

    Memory architecture also explains how binary digits are converted into electric signals and then stored in the memory cells. And also the structure of a memory cell. For example, dynamic memory is commonly used for primary data storage due to its fast access speed. However dynamic memory must be repeatedly refreshed with a surge of current ...

  7. Synchronous dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Synchronous_dynamic_random...

    It presents a two-bit bank address (BA0–BA1) and a 13-bit row address (A0–A12), and causes a read of that row into the bank's array of all 16,384 column sense amplifiers. This is also known as "opening" the row. This operation has the side effect of refreshing the dynamic (capacitive) memory storage cells of that row.

  8. Memory pool - Wikipedia

    en.wikipedia.org/wiki/Memory_pool

    Memory pools, also called fixed-size blocks allocation, is the use of pools for memory management that allows dynamic memory allocation. Dynamic memory allocation can, and has been achieved through the use of techniques such as malloc and C++'s operator new; although established and reliable implementations, these suffer from fragmentation ...

  9. new and delete (C++) - Wikipedia

    en.wikipedia.org/wiki/New_and_delete_(C++)

    Every call to new must be matched by a call to delete; failure to do so causes a memory leak. [1] new syntax has several variants that allow finer control over memory allocation and object construction. A function call-like syntax is used to call a different constructor than the default one and pass it arguments, e.g.,
