The downside of all of this refreshing is that it takes time and slows down the memory. Dynamic RAM has to be dynamically refreshed all of the time or it forgets what it is holding. This refresh operation is where dynamic RAM gets its name. This refresh operation happens automatically thousands of times per second. To do this, the memory controller reads the memory and then writes it right back. Therefore, for dynamic memory to work, either the CPU or the Memory Controller has to come along and recharge all of the capacitors holding it before they discharge.
WHAT IS STATIC RAM AND DYNAMIC RAM FULL
In a matter of a few milliseconds a full bucket becomes empty. The problem with the capacitor’s bucket is that it has a leak. The modules are installed in the PC’s motherboard using sockets – there are typically 2, 3 or 4 of these. Physically, RAM consists of small electronic chips which are mounted in modules (small printed circuit boards). In RAM, transistors make up the individual storage cells which can each “remember” an amount of data, for example, 1 or 4 bits – as long as the PC is switched on. RAM is made in electronic chips made of so called semiconductor material, just like processors and many other types of chips. RAM is considered “ random access” because you can access any memory cell directly if you know the row and column that intersect at that cell. so this mean RAM computer memory essentially empty.RAM holds data and processing instructions temporarily until the CPU needs it. As soon as the power is off, it can not be accessed. The RAM is a volatile memory, it means information written to it can be accessed as long as power is on. The User can write information to it and read information from it.With Ram any location can be reached in a fixed ( and short) amount of time after specifying its address. The Read and write (R/W) memory of a computer is called RAM. Random Access Memory ( RAM) is the best known form of C omputer Memory.
