    Can use Physical Address Extension to create a virtual disk in memory normally inaccessible to 32-bit versions of Microsoft Windows (both memory above the 4 GB point, and memory in the PCI hole). [13] There is also an open source plugin that replaces the RAM drive on Bart's PE Builder with one based on Gavotte's rramdisk.sys. [14]

    Protected memory was only added to Macintosh computers with the release of the Mac OS X operating system. According to Andy Hertzfeld, the Macintosh used for the introduction demo on January 24, 1984, was a prototype with 512k RAM, even though the first model offered for sale implemented just 128k of non-expandable memory. This prototype was ...

    en.wikipedia.org/wiki/RAM_drive

    The first software RAM drive for microcomputers was invented and written by Jerry Karlin in the UK in 1979/80. The software, known as the Silicon Disk System, was further developed into a commercial product and marketed by JK Systems Research which became Microcosm Research Ltd when the company was joined by Peter Cheesewright of Microcosm Ltd.

    Maximum capacity is 8 DIMM (16 GiB, PC1600-PC3200). Memory of different sizes can be mixed, but only if DIMMs of the same capacity are used in 1 bank (4 DIMM/bank). It supports non-volatile memory backup using an optional 2.5-inch PATA drive, HyperOs software (which swaps RAM contents to a different drive), or a backup battery (5 Ah or 10 Ah).

    Random Access Memory is memory storage that if found in electronic devices such as computers. It holds data while the computer is on so that it can be quickly accessed by the CPU or (Central Processing Unit). [3] Ram is different from regular storage units such as Hard Disks, Solid State Drives, and Solid State Hybrid Drives.

  7. Static random-access memory - Wikipedia

    Synchronous memory interface is much faster as access time can be significantly reduced by employing pipeline architecture. Furthermore, as DRAM is much cheaper than SRAM, SRAM is often replaced by DRAM, especially in the case when a large volume of data is required. SRAM memory is, however, much faster for random (not block / burst) access.

    The 9500 is also the first computer from Apple to support 168-pin DIMM memory modules, and the 512 KB of on-board 128-bit-wide cache utilizes copy-back instead of write-through, offering faster speeds than prior Macintosh models, [4] as well as the ability to install single modules (although matched pairs are recommended for best performance [6]).

  9. 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.
