CAS latency is short for Column Address Strobe latency. CAS latency is the time (in clock cycles) required to access a column of memory on a DRAM memory module. A CAS3 rated memory module requires 3 clock cycles to address a column of memory, where a CAS2 rated memory module can accomplish the

PROM stands for Programmable Read-Only Memory. It was invented by Wen Tsing Chow in 1956. Unlike a ROM chip, a PROM chip comes from the manufacturers devoid of any programming. Programming is done by the end user or the makers of electronic devices which require a permanent data storage device. Sinc

A hypervisor is a virtualization technique that runs multiple operating systems on the device. While non-hypervisor virtualization techniques run multiple operating systems on domestic computers and hand-held devices, hypervisors are used exclusively on devices whose sole task is to run multiple gue

Random-access memory is a type of data storage for computers. Commonly known as the acronym RAM or simply memory, random-access memory details the speed in which data that is stored can be accessed at random. This means that the strength of the RAM determines, at random, how fast a piece of data can

Random Access Memory (RAM) is a type of computer memory. It derives its name from the fact that any piece of data stored on it can be accessed at any time. RAM however stores data for as long as the computer is switched on or is in use. It is the most common type of computer memory available today.

ECC (Error Correction Codes) is a method used to detect and correct errors introduced during data storage or transmission. Certain kinds of RAM chips inside a computer implement this technique to correct data errors and are known as ECC Memory. ECC Memory chips are predominantly used in servers r

NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running

A SODIMM (Small Outline Dual Inline Memory Module) is a series of small DIMM chips that is specifically designed to fit into smaller working environments such as mobile devices and notebook computers. SODIMMs are designed to be smaller than regular DIMMs due to space restrictions, but provide the sa

Registered memory modules have built-in registers on their address and control lines. A register is a very small temporary holding area (usually 64 bits) for data. These registers act as buffers between the CPU and the memory. The use of registered memory increases system reliability, but a

DDR2 SDRAM, an abbreviation for double data rate two synchronous dynamic random access memory, is a type of a random access memory (RAM) commonly used in personal computers and various digital electronics today. This offspring from the SDRAM (synchronous dynamic random access memory), a part of DRAM
