    en.wikipedia.org/wiki/SoftRAM

    SoftRAM was designed for use with Windows 3.1.It was launched in March 1995 and sold more than 100,000 copies. [2]Most out-of-memory errors in Windows 3.x were caused by the first megabyte of memory in a computer, the conventional memory, becoming full.

  3. 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.

  5. Virtual memory - Wikipedia

    en.wikipedia.org/wiki/Virtual_memory

    Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".

  6. Extended memory - Wikipedia

    en.wikipedia.org/wiki/Extended_memory

    Extended memory is located above 1 MB, includes the high memory area, and ends at 16 MB on the Intel 286 and at 4 GB on the Intel 386DX and later.. In DOS memory management, extended memory refers to memory above the first megabyte (2 20 bytes) of address space in an IBM PC or compatible with an 80286 or later processor.

  7. Physical Address Extension - Wikipedia

    en.wikipedia.org/wiki/Physical_Address_Extension

    In computing, Physical Address Extension (PAE), sometimes referred to as Page Address Extension, [1] is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [2]

  8. Expanded memory - Wikipedia

    en.wikipedia.org/wiki/Expanded_memory

    The Expanded Memory Specification (EMS) is the specification describing the use of expanded memory. EMS functions are accessible through software interrupt 67h. Programs using EMS must first establish the presence of an installed expanded memory manager (EMM) by checking for a device driver with the device name EMMXXXX0.

  9. DOS memory management - Wikipedia

    en.wikipedia.org/wiki/DOS_memory_management

    The high memory area (HMA) is the RAM area consisting of the first 64 KiB, minus 16 bytes, of the extended memory on an IBM PC/AT or compatible microcomputer. Originally, the logic gate was a gate connected to the Intel 8042 keyboard controller. Controlling it was a relatively slow process.
