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 ...

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.

Without protected memory, it is possible that a bug in one program will alter the memory used by another program. This will cause that other program to run off of corrupted memory with unpredictable results. If the operating system's memory is corrupted, the entire computer system may crash and need to be rebooted. At times programs ...
The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system. Some of the address space may be shared between RAM, peripherals, and read-only memory.
