I-RAM, M-RAM: Good Bye to Hard Drives? by Marcelo Reyes
A couple of weeks ago, one of my lab associates made a comment about the advantages of the I-RAM and its speed with respect to the hard drive. What is an I-RAM? I asked. Simple. They are a bank of DDR memories that are used as a hard drive. They are powered through a PCI port and use a SATA... At the same time, while I was doing some research on I-RAMs I ran into some information about a new concept, the M-RAM (Magnetic Random Access Memory). ... Together with this, the MRAM requires less memory refresh than the capacitor based DRAMs and its theoretical velocity competes with that of the...

DVD RAM by Ken Marlborough
DVD is a format to store optical data. It is used as a storage medium for movies with very high video and sound quality. The DVD RAM or the DVD Read-And-Write Memory is a disk specification. The DVD Forum came up with it in 1996 and since 1998, DVD RAM has been used in computers, camcorders and... The name is a shortening of the words Read-And-Write Memory and not Random Access Memory. ... Though the optical drives shipped with the current Apple Macintosh computers do not support DVD RAM functions, a third party DVD RAM-compatible drive can be connected and used directly with Mac OS.

What Is Random Access Memory by Park Oskar
RAM is considered volatile storage because as soon as the power supply is stopped, the contents of RAM are lost. Hence, the data in RAM stays as long as the computer is running. RAM is much faster to read from and write to, when compared to other storage devices like hard disk, CDROM, Floppy... There are two fundamental types of RAM: (a) Dynamic RAM (DRAM) (b) Static RAM (SRAM) (a) Dynamic RAM (DRAM): Dynamic random access memory is the most common kind of RAM, which stores each bit of a data in a separate capacitor and a transistor.
