Computer Memeory

What is memory ?
A unit of computer which passel line of descent reading and entropy for retrieval at a subsequent period. stock refers to the capacity of storing in organizeation and the time in which information can be stored and retrieved. It is measured in bytes, kilobytes, megabytes or gigabytes

divers(prenominal) types of memory:-

Computer memory can be primarily be divided into two categories:-
1) ergodic Access fund
This is the same as main memory. When used by itself, the end point beat back refers to read and write memory; that is, we can some(prenominal) write data into RAM and read data from RAM. This is in contrast to ROM, which permits us only to read data. Most RAM is volatile, which means that it requires a steady flow of electricity to admit 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. Some of the variations of RAM are given below:-

a)Static Random Access Memory
SRAM is a type of memory that is faster and more reliable than the more common fluid drachm (dynamic RAM). The term static 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 pause between accesses.

Unfortunately, it is also much more expensive to produce than DRAM. 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 slower 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 get a full essay, order it on our website: Orderessay
