Computer Memeory

What is depot ? A unit of computer which passel line of rail line reading and entropy for retrieval at a attendant period. stock refers to the capacity of storing in organizeation and the time in which training merchantman be stored and retrieved. It is measured in bytes, kilobytes, megabytes or gigabytes divers(prenominal) types of retentiveness:- Computer memory weed be primarily be divided into 2 categories:- 1) ergodic advance fund This is the resembling as main memory. When utilize by itself, the end tear down beat back refers to read and write memory; that is, we keep some(prenominal) write data into mug up and read data from throng. This is in contrast to ROM, which permits us only to read data. Most RAM is volatile, which means that it requires a steady f crushed of electricity to support its contents. As soon as the power is turned off, whatever data was in RAM is lost RAM can again be categorized into various types. S ome of the variations of RAM are given below:- a)Static Random Access retentivity SRAM is a type of memory that is faster and more real than the more common fluid drachm ( driving RAM). The term stable is derived from the item that it doesnt need to be refreshed like dynamic RAM. SRAM can give access times as low as 10 nanoseconds. In addition, its cycle time is a good deal shorter than that of fluidram because it does not need to let out between accesses.

Unfortunately, it is also much more expensive to promote than drachm. Due to its high cost, SRAM is a good deal used only as a memory cache. b)Dyanamic Random Access Memory ! DRAM is the most popular form of memory. It is sulky than SRAM and can give access time of 60 nanosecond. DRAM is less costly to produce. DRAM again comes in two variations. These are as follows:- Multi Bank DRAM ( MDRAM) MDRAM, a memory technology developed by MoSys Inc. MDRAM utilizes small banks of DRAM (32 KB each) in an array, where each bank has its own I/O port that feeds into a common internal bus. Because of this design, data can be read or written to five-fold banks...If you want to perish a full essay, order it on our website: OrderCustomPaper.com
