A computer has two kinds of memory. The first is called primary storage, and is used to hold program instructions and data while the computer is running. The other kind, called secondary storage, is used for storage of data even while the computer is...

Random access memory (usually known by its acronym, RAM) is a type of computer data storage. It today takes the form of integrated circuits that allow the stored data to be accessed in any order, i.e. at random. The word random thus refers to the fact...

by Raymond Ambrose, Randa Creative In the search for on-chip RAM, SOI technology offers a new answer. Ever since its invention in the 1970s, DRAM (dynamic RAM) has been the most popular form of semiconductor memory. Indeed, modern computing and communication...

The functions, applications and memory refresh methods of the different Synchronous Dynamic Random Access Memory (SDRAM) and Synchronous Graphics Random Access Memory (SGRAM) controllers are presented. The autoprecharge controller is the simplest of the SDRAM and SGRAM controllers. The single-comparator model is best for...

South Korea's Samsung Electronics Co. expects strong demand and cost cuts to boost second-half profit in its chip business, it said Friday.The profit margin for its NAND flash memory chips _ used in digital consumer products like cameras and music players _ is rising sharply,...

IBM has devised a way to triple the amount of memory stored on computer chips and double the performance of data-hungry processors by replacing a problematic type of memory with a variety that uses much less space on the slice of silicon.International Business Machines Corp....
