So it needs to be refreshed 1000 times per second however it can have large number of cells. We have to keep refreshing it so that that data value is stored there till it is deleted. In DRAM each memory cell is made of one transistor and one capacitor what does that mean that means that the cell starts losing it charge the moment the data is stored there so we have to keep passing the charge and refreshing the memory.
The Random access memory is again of two types: The RAM is made up of semiconductor and flip flop. When the computer is powered off the data store in the RAM is lost therefore is called volatile memory. This is the broad type of primary memory as you can see here random access memory which is the RAM the read-only memory. The RAM memory data cannot be retrieving. RAM is random access memory which is also known as the main memory of the computer. The primary memory or main memory is of two types: The primary memory is father divided into two types:Īs you know primary memory is very expensive so technologies have been developed so that we can have different types of memory which can be optimized. Primary memory is that type of memory which directly communicates with the processor. So what are different types of memories? What are the uses of those memories and how they work collectively? We will discuss this in our article.Ĭomputer memory is divided in to two types:
There are layers of memory available in the computer that can make together and increase the performance of the computer. We cannot say that there is only one type of memory in our system that is working. Memory is one of the essential and important parts of the computer. We will also study about RAM, DRAM, SRAM, ROM, PROM, EPROM, EEPROM, UV EEPROM, Cache memory, Hard disk, CD/DVD drive, Pen Drive, and Blue-ray Disc. Computer Memory- In this article we will be looking at different types of the computer memories “Primary and Secondary Memories”.
