Computing and Information Systems: RAM & ROM

RAM Addresses
During the execution of a program, the contents of many RAM address locations are changed as the microprocessor updates the program, by storing intermediate or final results of operations performed.
Types of RAM
Like semiconductor ROM, semiconductor RAM has more than one type.

Whats a RAM?

In a few years, we can expect true non-volatile semiconductor RAMs, but for now, you have to design your memory application in such a way that the information is either no longer needed or stored somewhere else than in a semiconductor RAM during power down times. This really isnt nearly as bad as it seems ... Often a mixture of ROMs and RAMs in a single system does the job. There are two basic types of semiconductor RAMs. These are the static RAM and the ... read more

Computer Memory

Primary Memory. The fast and integrated memory of less capacity is termed as primary memory or main memory. The RAM, ROM, Flash memory, cache memory are types of primary memory. These memories have great effect on ... Primary Memory. Secondary Memory. 1. It is a semiconductor memory. It is a magnetic and optical memory. 2. In memory hierarchy, it is placed in highest position due to high speed, high cost and small size. In memory hierarchy, it is placed in lower position ... read more

Detecting and recovering from silent data errors in application ...

In an integrated storage replication environment, two types of storage errors need to be handled to prevent replica divergence, including hard errors and silent data errors. Hard errors, including complete disk ..... Examples of a computer- readable medium include a semiconductor or solid state memory,magnetic tape, a removable computer diskette, random access memory (RAM), read-only memory (ROM), a rigid magnetic disk, and an optical disk. Current examples of optical disks ... read more

Mobile News: Semiconductor memory on the march

Another important feature that distinguishes ROM from RAM, is that in order to save the contents of ROM does not require power. In memory storage elements which serve to ... Although this method allows you to store large amounts of data (from 500 MB to 1 GB) at a lower cost per 1 MB, it requires a slot Type III (the equivalent of two jacks Type II) and in an active state is a memory device consumes approximately ten times more power than flash memory. Flash memory has several ... read more
